[0002] In the electroanatomical mapping procedure, a catheter containing one or more sensing electrodes is inserted into the patient's heart, and the electrodes are used to acquire intracardiac electrogram signals. Based on the signals, an electroanatomical mapping of the heart is generated.

[0003] The disclosure incorporated herein by reference in U.S. Patent Application Publication 2018 / 0008203 describes electrocardiograms recorded in multiple channels. Pulses are automatically categorized into corresponding classes based on the morphological characteristics of the pulsations and their similarity to members of a set of templates. Corresponding electroanatomical mappings of the heart are generated from the categorized pulsations. Summary of the Invention

The processor is configured to display, in a graphical user interface (GUI) on the display, multiple desktop applets corresponding to different corresponding electroanatomical mappings generated from the electrograph signals while acquiring multiple electrograph signals from the heart. Each electroanatomical mapping is associated with a corresponding set of fitness criteria, such that any one of the electrograph signals is used to generate the mapping only if the signal meets the set of fitness criteria. The processor is further configured to, in response to a user selecting any of the desktop applets, display in the GUI the status of the most recently acquired electrograph signal among the electrograph signals relative to at least one of the set of fitness criteria associated with the electroanatomical mapping corresponding to the selected desktop applet.

[0007] In some implementations, the desktop applets include corresponding suitability indicators, and the processor is further configured to continuously update the suitability indicators of each desktop applet in the desktop applets while acquiring the electrodiagram signals, to indicate whether the most recently acquired electrodiagram signal in the electrodiagram signals meets the set of suitability criteria associated with the electrodiagram corresponding to the desktop applet.

[0008] In some implementations, the processor is configured to update the fitness indicator by changing its color.

[0009] In some implementations, the processor is also configured to label the desktop applets using an identifier of the electrophysiological mapping corresponding to each desktop applet in the desktop applets.

[0010] In some implementations, the electroanatomical mapping is associated with a corresponding signal template because the set of suitability criteria for each mapping includes criteria that match the signal template.

[0011] In some implementations, the processor is further configured to label the desktop applets using an identifier of the signal template associated with the electrophysiological mapping corresponding to each desktop applet in the desktop applets.

[0012] In some implementations, the desktop applets include corresponding template matching indicators, and the processor is further configured to continuously update the template matching indicator of each desktop applet in the desktop applets when acquiring the electrodiagram signal, to indicate whether the most recently acquired electrodiagram signal in the electrodiagram signal matches the template associated with the electrodiagram corresponding to the desktop applet.

[0013] In some implementation schemes,

[0014] The processor is configured to display the desktop applet in the first part of the GUI, and

[0015] The processor is configured to display the status in the second part of the GUI while continuing to display the desktop applet.

[0016] According to some embodiments of the present invention, a method is also provided, the method comprising, while acquiring multiple electrographing signals from the heart, displaying in a graphical user interface (GUI) a plurality of desktop applets corresponding to different corresponding electroanatomical mappings generated from the electrographing signals, each of the electroanatomical mappings being associated with a corresponding set of fitness criteria, such that any one of the electrographing signals is used to generate the mapping only if the signal satisfies the set of fitness criteria. The method further comprises, in response to a user selecting any of the desktop applets, displaying in the GUI the status of the most recently acquired electrographing signal among the electrographing signals relative to at least one of the set of fitness criteria associated with the electroanatomical mapping corresponding to the selected desktop applet.

[0017] According to some embodiments of the present invention, a computer software product is also provided, comprising a tangible, non-transitory, computer-readable medium therein storing program instructions. When read by a processor, the instructions cause the processor to display, in a graphical user interface (GUI), multiple desktop applets corresponding to different corresponding electroanatomical mappings generated from the electrocardiogram signals while acquiring multiple electrocardiogram signals from the heart. Each electroanatomical mapping is associated with a corresponding set of fitness criteria, such that any one of the electrocardiogram signals is used to generate the mapping only if the signal satisfies the set of fitness criteria. The instructions also cause the processor, in response to a user selecting any of the desktop applets, to display in the GUI the status of the most recently acquired electrocardiogram signal among the electrocardiogram signals relative to at least one of the set of fitness criteria associated with the electroanatomical mapping corresponding to the selected desktop applet.

[0023] Overview

[0024] In some applications, such as those described in U.S. Patent Application Publication 2018 / 0008203, multiple different electroanatomical maps of the heart are generated in parallel, i.e., generated from a single electrodiagnostic signal acquisition session. The electroanatomical maps may correspond to, for example, different corresponding arrhythmic states exhibited by the patient during the session. Alternatively or otherwise, the electroanatomical maps may display different types of information or may be generated from different sets of electrodiagnostic signals.

[0025] In such applications, a corresponding set of suitability criteria is specified for the mapping, and the signal is used to generate a specific mapping only if each acquired signal meets the suitability criteria of the mapping. Suitability criteria may include, for example, a criterion that the correlation score between the signal and a predefined signal template exceeds a predefined threshold. Alternatively or otherwise, suitability criteria may include criteria related to the characteristics of the cardiac cycle of the acquired signal, or criteria related to the stability of the catheter during signal acquisition.

[0026] When performing parallel mapping as described above, the challenge is that physicians may find it difficult to track the progress of the mapping procedure in real time due to the multiple mapping maps.

[0027] To address this challenge, embodiments of the present invention provide a graphical user interface (GUI) for parallel mapping. The GUI includes multiple desktop applets, such as buttons or labels, typically arranged in rows or columns. Each desktop applet corresponds to a different corresponding mapping plot. As a physician selects any of the desktop applets, the GUI displays the status of the most recently acquired electrogram signal relative to a suitability criterion used for the corresponding mapping plot. For example, the GUI may display a correlation score between the signal and a signal template, along with an indication of whether that score exceeds a correlation threshold.

[0028] Advantageously, each desktop app can indicate whether the signal meets the suitability criteria, allowing physicians to easily determine this information even without selecting a desktop app. Alternatively or additionally, the desktop app can include other higher-level information, such as the aforementioned correlation score. Alternatively or additionally, the desktop app can include the name of the mapping plot and / or the name of the signal template used for the mapping plot.

[0029] System Description

[0030] First refer to Figure 1 This is a schematic diagram of a system 20 for real-time tracking of parallel electroanatomical mapping procedures according to some embodiments of the present invention.

[0031] Figure 1 The illustration shows a physician 26 performing parallel electroanatomical mapping of the chambers of the heart 24 of patient 22. To perform the mapping, physician 26 inserts catheter 28 into the chamber. The physician then uses one or more electrodes positioned at the distal end of catheter 28 (which may be referred to as a “probe”) to acquire electrogram signals from the chamber.

[0032] Typically, one electrogram signal is acquired during each heart cycle 24. In some cases, each acquired signal is a single-channel signal. For example, the signal may represent the voltage between a single electrode at the distal end of catheter 28 and an external electrode disposed on the patient's body. Alternatively, the signal may represent the voltage between a pair of electrodes at the distal end of catheter 28. In other cases, each acquired signal is a multi-channel signal. For example, the distal end of catheter 28 may include multiple pairs of electrodes, and each pair of electrodes may acquire a signal from a corresponding channel.

[0033] System 20 includes a processor 34. During the acquisition of electrogram signals, processor 34 receives signals from conduit 28. For example, the processor may be located within console 30, and the proximal end of the conduit may be connected to console 30 via an electrical interface 32, such as a port or socket, so that each acquired signal passes through the conduit and enters the console via interface 32. After passing through analog-to-digital conversion circuitry and any other related circuitry, each signal can be received by processor 34.

[0034] Based on the received electrodiagram signals, the processor generates multiple electroanatomical mappings. Each electroanatomical mapping is associated with a corresponding set of fitness criteria, such that any particular electrodiagram signal is used to generate the mapping only if the signal meets the set of fitness criteria. For example, an electroanatomical mapping may be associated with a corresponding signal template, because the set of fitness criteria used for each mapping may include criteria for matching the signal template. In other words, any particular electrodiagram signal can only be used to generate the mapping if the signal matches the signal template.

[0035] In some implementations, electroanatomical mapping is generated in multiple stages. For example, each electroanatomical mapping may be initialized from pre-acquired anatomical mappings of the chamber prior to the procedure. After initialization, the mappings may be continuously updated as electrogram signals are acquired. Alternatively, each mapping may be initialized during the procedure based on both electrical and anatomical information acquired during that procedure, and subsequently continuously updated as additional electrogram signals are acquired. In other implementations, the electroanatomical mapping is generated in a single step after all electrogram signals have been acquired.

[0036] The system also includes a display 36, which may include, for example, a desktop or laptop computer monitor. During and / or after the mapping procedure, the processor 34 may display one or more electroanatomical mappings on the display 36. Furthermore, during signal acquisition, the processor 34 displays a graphical user interface (GUI) 38 on the display 36. The GUI 38 includes a plurality of desktop applets 40 corresponding to the electroanatomical mappings, each applet including one or more tabs and / or one or more buttons. Typically, the desktop applets 40 are arranged in rows or columns.

[0037] System 20 also includes one or more input devices, such as a keyboard or mouse. Alternatively or in addition, display 36 may be used as an input device, as the display may include a touchscreen. Using any of these input devices, a user of the system, such as physician 26, may select any of the desktop applets 40. For example, the user may hover the mouse pointer over the desktop applet and then click the mouse button, or if the display includes a touchscreen, simply touch the screen at the location of the desktop applet.

[0038] In some implementations, the processor identifies each desktop applet using an identifier 48 of the electroanatomical mapping corresponding to the applet. Alternatively or additionally, the processor may identify each desktop applet using an identifier 50 of a signal template associated with the corresponding electroanatomical mapping. Each identifier in identifiers 48 and 50 may include any suitable sequence of letters, numbers, and / or other characters, which may be entered by the user (or another user) at any time prior to the procedure, for example, using a keyboard. Figure 1 In the middle, the leftmost desktop applet has two labels: "1-NSR", which indicates the first mapping map by its number ("1") and name ("NSR"); and "NSR:1", which similarly indicates the template associated with the first mapping map by its number ("1") and name ("NSR").

[0039] In response to a user selecting any of the desktop applets 40, the processor displays the status of the most recently acquired electrogram signal in the GUI relative to at least one of a set of suitability criteria (e.g., each criterion) associated with the electrophysiological mapping corresponding to the selected desktop applet. Typically, the processor displays the status while continuing to display the desktop applet. For example, the desktop applet may be displayed in a first portion 44 of the GUI, while the status of the most recently acquired electrogram signal may be displayed in a second portion 46 of the GUI, which may be located, for example, below the first portion 44. In some embodiments, particularly where the desktop applet is not a label, the processor modifies the appearance of the selected desktop applet, for example, by displaying a border 42 surrounding the desktop applet, to indicate that the desktop applet has been selected.

[0040] For example, Figure 1 The diagram shows a scenario where the user has selected the fourth desktop app on the far right. In response to this selection, the processor displays the status of the most recently acquired electrogram signal relative to a set of suitability criteria associated with the fourth mapping.

[0041] Typically, the processor displays the status of the most recently acquired electrogram signal by displaying multiple indicators, each indicating whether the signal meets a different corresponding criterion in the standard.

[0042] For example, the processor may display indicator 54, which indicates whether the signal matches the template associated with the mapping map (in...). Figure 1 This is referred to as a "pattern" ("PTRN"). For example, if the correlation score 56 between the signal and the template exceeds a predetermined threshold, the signal can be considered a match. The correlation score 56 can also be displayed in the second part 46, for example, within the indicator 54.

[0043] In addition to displaying indicator 54, or alternatively, the processor may display a channel-specific indicator 58 for each channel and for each channel-specific standard, indicating whether the channel meets the channel-specific standard. For example, in Figure 1 In the text, channel-specific indicators 58 are displayed for each of channels 1-2, 3-4, ..., 19-20, and for each channel-specific standard designated as "POS" and "DEN". (Each pair of numbers in the channel list refers to a different corresponding electrode pair.)

[0044] In some implementations, indicator 54 includes a portion of the GUI (e.g., a rectangular or circular portion) colored with a first color 62 (e.g., green) when the signal matches the template and with a second color 64 (e.g., red) when the signal does not match. Similarly, each channel-specific indicator 58 may include a portion of the GUI (e.g., a rectangular or circular portion) colored with a first color 62 when the criterion is met and with a second color 64 otherwise. A third color 66 (e.g., gray) may be used to indicate the absence of a channel-specific criterion and / or to indicate that no acquisition was performed on the channel.

[0045] Typically, the desktop app 40 includes a corresponding suitability indicator 52. During the acquisition of electrogram signals, the processor continuously updates the suitability indicator 52 of each desktop app to indicate whether the most recently acquired electrogram signal meets a set of suitability criteria associated with the corresponding mapping. As described above, the signal is used to generate the mapping only if it meets the suitability criteria.

[0046] For example, the suitability indicator 52 may include a portion of a desktop app, the color of which is continuously changed by the processor. In other words, after acquiring each signal, if the signal meets the suitability criteria, the processor may set the color of the suitability indicator to a first color (e.g., green), otherwise to a second color (e.g., red). In some implementations, such as... Figure 1As shown, the suitability indicator 52 includes a relatively small portion of the desktop applet, such as a horizontal bar along the bottom of the desktop applet. In other embodiments, the suitability indicator 52 includes most or all of the desktop applet, such as, for example... Figure 2 As shown (as described below).

[0047] Typically, a set of suitability criteria can specify any minimum number of channels that must meet channel-specific criteria. For example, a signal can be considered to meet a set of suitability criteria if at least one channel meets every channel-specific criterion in the channel-specific criteria, provided that no non-channel-specific criteria are met.

[0048] In some implementations, the processor modifies the fit indicator 52 to indicate the number of channels that meet each channel-specific criterion in the channel-specific criteria. For example, the processor may change the hue of the fit indicator 52 according to the number of channels, such that, for example, a lighter or darker green hue indicates a larger number of channels. Alternatively or otherwise, the processor may change the size of the fit indicator 52 according to the number of channels. For example, if the fit indicator includes, for example, Figure 1 The processor can change the length of the horizontal bar shown. Alternatively or otherwise, the suitability indicator may include an explicit indication of the number of channels, such that, for example, "3 / 10" indicates that three out of ten channels meet the channel-specific criteria for each channel.

[0049] In some implementations, the GUI can be displayed in either a fully open mode or a partially open mode. In fully open mode, both the first portion 44 and the second portion 46 of the GUI are displayed, as shown below. Figure 1 As shown. In the partially open mode, only the first portion of the desktop applet 40 is displayed. Any suitable input from the user (e.g., received via mouse or keyboard) can switch between the two modes. Thus, for example, when the GUI is fully open, in response to receiving mode-switching input, the processor can close the second portion 46, such that only the first portion 44 is displayed; conversely, when the GUI is only partially open, the processor can open the second portion 46 in response to mode-switching input. (In some embodiments, the second portion of the GUI is closed when the GUI is initially displayed. In other embodiments, the second portion of the GUI is initially open, and one of the desktop applets, such as the leftmost desktop applet, is initially assumed to be selected by default.)

[0050] Generally, processor 34 may be embodied as a single processor or a group of cooperative networked or clustered processors. In some embodiments, as described herein, the functionality of processor 34 may be implemented solely in hardware, such as using one or more application-specific integrated circuits (ASICs) or field-programmable gate arrays (FPGAs). In other embodiments, the functionality of processor 34 is implemented at least partially in software. For example, in some embodiments, processor 34 is embodied as a programmable digital computing device including at least a central processing unit (CPU) and random access memory (RAM). Program code (including software programs and / or data) is loaded into RAM for execution and processing by the CPU. For example, program code and / or data may be downloaded to the processor electronically via a network. Alternatively or otherwise, program code and / or data may be provided and / or stored on a non-transitory tangible medium, such as magnetic, optical, or electronic memory. Such program code and / or data, when provided to the processor, create a machine or special-purpose computer configured to perform the tasks described herein.

[0051] Now for reference Figure 2 This is a schematic diagram of a desktop applet 40 according to some embodiments of the present invention.

[0052] In some implementations, each desktop applet includes a corresponding template matching indicator 60. During the acquisition of electrogram signals, the processor continuously modifies the template matching indicator 60 for each desktop applet to indicate whether the most recently acquired signal matches a template associated with the electrogram mapping corresponding to that desktop applet. For example, the template matching indicator may include a portion (e.g., a rectangular or circular portion) of the desktop applet that is colored by the processor with a first color (e.g., green) when the signal matches the template and with a second color (e.g., red) when the signal does not match. Optionally, the processor may also display an identifier 50 and / or a correlation score 56 within the template matching indicator. (In some such implementations, indicator 54 may be omitted from the second part 46 of the GUI.)

[0053] (Note that even if a signal matches the template, it may still not meet a set of suitability criteria. Therefore, as...) Figure 2 As shown, template matching indicator 60 can be colored differently from suitability indicator 52.

[0054] It should be emphasized that, although Figure 1-2 Specific examples are shown, but the scope of the invention includes any suitable design for GUI 38 and desktop applet 40.

[0055] Exemplary Algorithm

[0056] Now for reference Figure 3AThis is a flowchart of a first GUI display algorithm 68 according to some embodiments of the present invention.

[0057] In the first GUI display algorithm 68, the processor continuously checks at the first checking step 70 whether a new signal has been received from the conduit. Upon determining that a new signal has been received, the processor processes the signal at the signal processing step 72. For example, the processor may determine whether each channel of the signal meets the relevant channel-specific criteria and / or calculate a correlation score between the signal and a predefined signal template.

[0058] After processing the signal, the processor updates the desktop applet in the first part of the GUI based on the signal processing at desktop applet update step 74. For example, the processor may change the color of the suitability indicator for one or more desktop applets. (Desktop applet update step 74 is not performed if the desktop applet contains only static information such as a mapping map name, or if updating the desktop applet is not required.)

[0059] After the desktop applet update step 74, the processor checks in the second check step 76 whether the second part of the GUI is open. If so, the processor updates the state of the signals in the second part of the GUI in the state update step 78 based on signal processing relative to the selected desktop applet (i.e., relative to the mapping map corresponding to the selected desktop applet). For example, the processor may change the color of one or more channel-specific indicators. (State update step 78 is not performed if no state update is required.) After state update step 78, or if the second part of the GUI is closed, the processor returns to the first check step 70.

[0060] Now for reference Figure 3B This is a flowchart of a second GUI display algorithm 80 according to some embodiments of the present invention. Typically, the processor executes the second GUI display algorithm 80 in parallel with the first GUI display algorithm 68.

[0061] In the second GUI display algorithm 80, the processor continuously checks at the third checking step 82 whether another desktop applet different from the currently selected desktop applet has been selected by the user. If so, the processor displays the status of the most recently received signal in the second part of the GUI relative to the selected desktop applet at the status display step 84. (If the second part of the GUI was closed when the desktop applet was selected, the processor may open the second part of the GUI before executing the status display step 84.)

[0062] After status display step 84, or if no other desktop app is selected, the processor checks at fourth check step 86 whether input for opening or closing the second part of the GUI has been received. If so, the processor opens or closes the second part of the GUI based on the input at open or close step 88. Subsequently, or if no input for opening or closing the second part of the GUI has been received, the processor returns to third check step 82.

[0063] Those skilled in the art will understand that this invention is not limited to what has been specifically shown and described above. Rather, the scope of embodiments of this invention includes both combinations and sub-combinations of the various features described above, as well as variations and modifications outside the scope of the prior art that may occur to those skilled in the art upon reading the foregoing specification. Documents incorporated herein by reference are considered an integral part of this application, except that if any terminology defined in such incorporated documents conflicts with the definitions expressly or implicitly given in this specification, only the definitions in this specification shall be considered.
