Abstract

The invention discloses an ECG waveform simulation method, and relates to the field of medical education. The method comprises the steps: 1, acquiring ECG waveform data: acquiring a clinical electrocardiogram, identifying an electrocardiogram curve, obtaining point coordinate data uniformly distributed in the time dimension, and marking a P wave start point, a QRS wave group start point, and a T wave end point; 2, judging the shape of an ECG waveform: segmenting the ECG waveform data according to a cardiac cycle, judging whether all segments of the cardiac cycle waveform after segmentation areconsistent not, marking a main rhythm waveform and an ectopic rhythm waveform, further segmenting the main rhythm waveform, and performing breakpoint smoothing of segmented waveforms; 3, performing dynamic simulation: obtaining a current heart rate by fine-tuning control, calculating the length of the TP segment under an original heart rate and the current heart rate, generating a main rhythm waveform and an ectopic rhythm waveform under the current heart rate, and performing the outputting. According to the present invention, the method achieves the dynamic display of a clinical real electrocardiogram and enriches the clinical teaching examples.

Description

technical field [0001] The invention relates to the field of medical teaching, in particular to a method for simulating an electrocardiogram waveform. Background technique [0002] The heart is the power plant of the human blood circulation. It is precisely because the heart automatically and continuously performs rhythmic contraction and relaxation activities that blood flows continuously in the closed circulatory system and life is maintained. Before and after the heart beats, the heart muscle is excited. During the exciting process, a weak biological current will be generated. In this way, every cardiac cycle of the heart is accompanied by bioelectrical changes. This bioelectrical change can be transmitted to various parts of the body surface. Due to the different tissues of different parts of the body and the different distances from the heart, the electrocardiographic signal exhibits different potentials in different parts of the body. For a normal heart, the direc...
