Description

Technical Field

[0001] The present invention relates to the technical field of electrocardiogram, and particularly to an electrocardiogram display method, a display device, a medium and a program product. Background Art

[0002] Electrocardiogram (ECG) is an important tool for clinical diagnosis of heart diseases. Doctors analyze ECG data to judge the heart health status of patients. Traditional ECG analysis systems usually adopt fixed display parameter settings, such as lead layout, paper speed, gain, and starting position, etc. However, due to the large differences in ECG data of different patients, the fixed display parameter settings may lead to low diagnostic efficiency or misdiagnosis. For example, when there is interference at the starting position of the electrocardiogram, doctors need to manually adjust the starting position to obtain a clear signal; when the heart rate is too fast, the fixed paper speed may make it difficult to observe the P, QRS, and T waves; when there is high voltage in the chest leads, the default lead layout and gain may not be able to effectively display the data. Therefore, there is an urgent need for a method that can automatically adjust the display parameters according to the characteristics of electrocardiogram data to improve the accuracy and efficiency of diagnosis.

The components in the drawings are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0037] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation manners.

[0038] Embodiment 1:

[0039] Figure 1 The following is a schematic flowchart of an electrocardiogram display method according to an embodiment of the present invention. The method of this embodiment includes the following steps:

[0040] Obtain electrocardiogram data of a first electrocardiogram, including measured values of predetermined indicators, diagnosis results, diagnosis feature positions, and start and end segment positions of interference. Among them, the diagnosis feature positions are related to the diagnosis results; the predetermined indicators include heart rate, electrocardiogram axis degree, P wave, QRS complex, QT interval, PR interval, ST segment, and T wave; in a specific implementation, the corresponding electrocardiogram data is obtained from the first electrocardiogram by using a predetermined electrocardiogram analysis algorithm; among them, the first electrocardiogram is output with the first electrocardiogram display parameters set; in a specific implementation, the first electrocardiogram display parameters are set to the preset default electrocardiogram display parameter settings; for the patient currently undergoing electrocardiogram detection, first, the electrocardiogram data currently collected is displayed and output as the first electrocardiogram using the above-mentioned predetermined default electrocardiogram display parameters; then, a predetermined electrocardiogram analysis algorithm, such as an existing electrocardiogram analysis algorithm or product, is used to analyze the first electrocardiogram to obtain the electrocardiogram data including the above-mentioned content; it should be noted that the diagnosis feature position is a specific part on the electrocardiogram waveform that reflects the diagnosis result, such as a heart disease or an abnormal condition, and the start and end segment position of interference is the part between the starting point and the ending point where interference appears in the electrocardiogram waveform;

[0041] The selected position in the first predetermined time period before the diagnostic feature position or the selected position in the second predetermined time period after the interference start-stop segment position is determined as the output start position of the second electrocardiogram. In a specific implementation, the predetermined first time period is several seconds, preferably 1 s, that is, the position 1 s before the diagnostic feature position is selected as the output start position; the predetermined second time period is several seconds, preferably 1 s, that is, the position 1 s after the interference start-stop segment position is selected as the output start position. For example, Figure 2 is an example of the appearance of diagnostic features in an electrocardiogram according to an embodiment of the present invention, Figure 2 which shows that the electrocardiogram shows diagnostic features at 6.5 s, and the diagnostic result is determined to be "ventricular premature beat". In order to better display the electrocardiogram, the electrocardiogram will be output at the selected position at a first predetermined time period such as 5.5 s before the diagnostic feature position to eliminate the bands unrelated to the diagnosis in the front, thereby improving the diagnostic efficiency. Figure 3 is a schematic diagram of the appearance of the interference start-stop segment in an electrocardiogram according to an embodiment of the present invention, Figure 3 which shows that the electrocardiogram has an interference segment at 0-20 s. In order to exclude the influence of interference on the electrocardiogram output, the electrocardiogram will be output at the selected position at a second predetermined time period such as 21 s after the interference start-stop segment position to eliminate the interference start-stop segment.

[0042] According to the measured values and diagnostic results of the first electrocardiogram and the preset configuration library, the electrocardiogram display parameters of the second electrocardiogram are determined, where the preset configuration library presets the corresponding relationship between the measured values of the predetermined indicators, the diagnostic results, and the electrocardiogram display parameter settings. The electrocardiogram display parameters include: lead layout, paper speed, gain, and a synchronous mode enable flag for indicating whether to enable the synchronous mode and / or a continuous mode enable flag for indicating whether to enable the continuous mode. In the synchronous mode, the starting time positions of different columns of the electrocardiogram are the same; in the continuous mode, the starting time positions of different columns of the electrocardiogram are different;

[0043] Adjust the first electrocardiogram according to the output start position of the second electrocardiogram and the electrocardiogram display parameter settings of the second electrocardiogram, and output the second electrocardiogram.

[0044] Using the electrocardiogram display method according to the embodiments of the present invention, for different patients, after outputting the first electrocardiogram using the default electrocardiogram display parameter settings of the existing electrocardiogram display device, it further includes selecting, from a predetermined configuration library, the electrocardiogram display parameter settings corresponding to the current measured values and / or diagnosis results of the patient according to the current electrocardiogram index measured values and / or diagnosis results of the patient, and adjusting the original default display parameter settings according to the electrocardiogram display parameter settings to output the second electrocardiogram corresponding to the measured values and / or diagnosis results of the patient, thereby realizing the automatic adjustment of the electrocardiogram display parameters according to the actual situation of the electrocardiogram data. Further, using this embodiment, by determining the output start position of the second electrocardiogram according to the diagnostic feature position or the interference start and end segments position, the corresponding interference segments or irrelevant segments can be removed. For example, the local electrocardiogram waveform related to the diagnosis result in the first electrocardiogram is extracted as the second electrocardiogram, and the second electrocardiogram is displayed using more appropriate electrocardiogram display parameters selected from the preset configuration library, so that the electrocardiogram can be displayed in a manner that is more convenient for doctors to observe.

[0045] Further, configuring and adjusting the corresponding electrocardiogram display parameters from the preset configuration library includes one or more of the following:

[0046] When the heart rate is less than 40 bpm, according to the pre-configured correspondence between the heart rate and the paper speed, the paper speed is automatically adjusted to 12.5 mm / s to extend the waveform display time and facilitate the observation of more heartbeats;

[0047] When the heart rate is greater than 120 bpm, according to the pre-configured correspondence between the heart rate and the paper speed, the paper speed is automatically adjusted to 50 mm / s to ensure the clear display of the P, QRS, and T waves;

[0048] When the diagnosis result, such as the automatic diagnosis result, is including parasystole, according to the pre-configured correspondence between the parasystolic heart rate and the lead layout, the lead layout is adjusted to a single-column mode to facilitate the observation of the characteristics of parasystole;

[0049] When the diagnosis result, such as the automatic diagnosis result, is including right ventricular hypertrophy or left ventricular hypertrophy, according to the pre-configured correspondence between right ventricular hypertrophy or left ventricular hypertrophy and the lead layout, the lead layout is adjusted to a 3-row and 4-column mode, and the chest lead gain halving mode is turned on to optimize the display of high-voltage leads and avoid the superposition of waveforms of different leads. In a specific implementation, when the gain is 10 mm / mV, the chest lead gain is 5 mm / mV after the chest lead gain halving mode is turned on;

[0050] When the automatic diagnosis result is including low voltage, according to the pre-configured correspondence between low voltage and the gain, the gain is automatically adjusted to 20 mm / mV to facilitate the detailed analysis of the low-voltage characteristics of each lead;

[0051] When the automatic diagnosis result includes premature beats, according to the pre-configured correspondence between premature beats and mode identifiers, it is adjusted to enable the synchronous mode to ensure that the starting points of waveforms of all leads are consistent, facilitating the localization of the source of premature beats.
