It should be noted that if there are substantially the same results, the method of the present application is not based on Figure 1 The process sequence shown is limited. This method can be applied to an electrocardiograph 200 having functions such as calculation, etc., see Figure 2 , Figure 2 The electrocardiograph 200 includes a memory 201, a processor 202 and a display 203, which are coupled to each other. The processor 202 is used to execute the program instructions stored in the memory 201 to implement the steps in the embodiment of the electrocardiograph spectrum display method. The display 203 is used to display the results obtained by the processor 202 executing the program instructions.

[0030] Specifically, the processor 202 is used to control itself and the memory 201 to implement the steps in the embodiment of the above-mentioned ECG spectrum display method. The processor 202 can also be called a CPU (Central Processing Unit), and the processor 202 may be an integrated circuit chip with signal processing capabilities.

The general-purpose processor can be a microprocessor or the processor can also be any conventional processor, etc. In addition, the processor 202 can be implemented by an integrated circuit chip.

[0031] The electrocardiograph 200 may execute the method by receiving relevant information. Figure 1 As shown, the electrocardiogram spectrum display method includes the following steps:

[0032] S1. Receive and respond to an instruction to trigger spectrum graphic display, and acquire ECG data.

[0033] To obtain ECG data, it is understandable that, depending on the different clinical manifestations of the patient, different ECG lead systems are usually selected to collect the patient's ECG data. For example, the ECG lead system can be a 12-lead system, a 16-lead system, or an orthogonal lead system.

[0034] Taking the 12-lead system as an example, the 12-lead system includes 12 ECG leads, specifically, lead I, lead II, lead III, aVR lead, aVL lead, aVF lead, V1 lead, V2 lead, V3 lead, V4 lead, V5 lead, and V6 lead. Each lead is connected to a corresponding position of the human body, so as to collect ECG data of lead I, lead II, lead III, aVR lead, aVL lead, aVF lead, V1 lead, V2 lead, V3 lead, V4 lead, V5 lead, and V6 lead of the human body through electrodes on the human body surface, that is, the ECG data includes ECG data of at least one lead.

[0035] S2. Analyze the ECG data on at least one interface to obtain ECG signal frequency domain information.

[0036] Receiving and responding to the instruction to trigger the display of the spectrum graph, analyzing the acquired ECG data on at least one interface can obtain the corresponding ECG signal frequency domain information. It can be understood that analyzing the ECG data of at least one lead can obtain the ECG signal frequency domain information of at least one lead.

[0037] In the process of analyzing the ECG data, the ECG data may be subjected to a fast Fourier transform (FFT) to obtain the ECG signal frequency domain information. In other embodiments, other feasible methods may be used to analyze the ECG data, which may be selected according to actual use requirements without specific limitation.

[0038] S3. Based on the frequency domain information of the ECG signal, draw and display at least one lead power spectrum diagram and / or dual-lead analysis diagram on at least one interface.

[0039] After obtaining the ECG signal frequency domain information, at least one lead power spectrum diagram and / or dual-lead analysis diagram is drawn and displayed on the at least one interface according to the ECG signal frequency domain information. It can be understood that at least one lead power spectrum diagram can be drawn according to the ECG signal frequency domain information of at least one lead; and the dual-lead analysis diagram of any two leads can be drawn according to the ECG signal frequency domain information of any two leads.

[0040] At least one lead power spectrum diagram, such as the twelve lead power spectrum diagrams corresponding to the 12 leads, is a power spectrum diagram of each lead drawn with frequency as the horizontal axis and power as the vertical axis. It can be understood as a distribution diagram of the power size of each frequency component in the frequency domain information of the ECG signal.

[0041] Wherein, when at least one lead power spectrum diagram and the dual-lead analysis diagram are displayed simultaneously, at least one lead power spectrum diagram and the dual-lead analysis diagram are displayed separately on at least one interface.

[0042] For example, when at least one lead power spectrum graph and the dual-lead analysis graph are displayed on the same interface, at least one lead power spectrum graph is displayed on half of the interface, and the dual-lead analysis graph is displayed on the other half of the interface; or, when at least one lead power spectrum graph and the dual-lead analysis graph are displayed on two interfaces, at least one lead power spectrum graph is displayed on one interface, and the dual-lead analysis graph is displayed on the other interface.

[0056] It is understandable that the adjustable state instruction can be triggered by clicking on a preset position on at least one interface, so that at least one lead power spectrum graph is in an adjustable state. The preset position can be set according to actual use requirements, such as setting an adjustable control separately, or other achievable methods, without specific limitation.

[0057] Receiving and responding to the instruction to trigger the adjustable state, controlling at least one lead power spectrum graph to be in an adjustable state on at least one interface, and then adjusting at least one lead power spectrum graph as needed. For example, adjusting at least one lead power spectrum graph to realize a zoomed-in display mode, a zoomed-out display mode, a single-screen display mode, or other achievable display modes are all possible, without specific limitation, to facilitate on-demand viewing.

[0058] In one embodiment of the present application, at least one lead power spectrum diagram and / or dual-lead analysis diagram is drawn and displayed on at least one interface based on the frequency domain information of the electrocardiogram signal, further comprising: at least one lead power spectrum diagram is displayed on at least one interface according to a first preset order, and in response to an instruction to trigger a display change, at least one lead power spectrum diagram is controlled to be displayed on at least one interface according to a second preset order, wherein the second preset order is different from the first preset order; or, in response to an instruction to trigger a display change, at least one selected one of the at least one lead power spectrum diagram is obtained for single-screen or split-screen display; or, in response to an instruction to trigger a display change, at least one selected one of the at least one lead power spectrum diagram is controlled for zoomed display.

[0064] Wherein, in the same coordinate system, the frequency is used as the horizontal coordinate and the power is used as the vertical coordinate, so as to draw the corresponding two-lead power spectra based on the frequency domain information of the ECG signals of the two leads to obtain a dual-lead power spectrum, so as to perform a comparative view in the same coordinate system.

[0067] With frequency as the horizontal coordinate and coherence value as the vertical coordinate, a coherence function diagram corresponding to the frequency domain information of the ECG signals of two leads is drawn to obtain a dual-lead coherence function diagram. The coherence value represents the relative relationship between the frequency domain information of the ECG signals of the corresponding two leads, a coherence value of 1 indicates complete coherence, and a coherence value of 0 indicates complete incoherence. The relative relationship between the frequency domain information of the ECG signals of two leads represents the measure of the correspondence of the amplitude, frequency and phase angle between the frequency domain information values ​​of the ECG signals of the two leads.

In addition, in some embodiments, the ECG signal frequency domain information of the selected two leads is obtained in response to the instruction to trigger the update of the dual-lead analysis diagram, and the corresponding dual-lead pulse response diagram is drawn and updated based on the ECG signal frequency domain information of the selected two leads.

[0069] The dual-lead mutual interference diagram is used to characterize the frequency domain correlation of the dual leads, and the cross-correlation function curve presents several peaks with similar shapes and equal intervals. Among them, the frequency domain information of the ECG signals of the two leads corresponding to the dual-lead mutual interference diagram can be the frequency domain information of the ECG signals of any two leads, which can be selected as needed.
