Abstract:
Objective To research and construct dynamic electrocardiograph (ECG) simulation model/algorithm to simulate different kinds of clinical ECG,where the heart rate can be infinitely variable,and to develop one platform for fast-demo and analysis of theoretical wave based on this algorithm which can be implemented in ECG training and teaching. Methods According to different characteristics decoupled one complete ECG wave to 4 parts,including P-wave,PR-section,QT -wave and TP -section. P -wave and QT -wave database were set up accordingly to find the relationship algorithm between PR-section and heart rate,TP-section and heart rate. With the synthesis work of the algorithm and clinical diagnosis theory,ECG simulation mathematical model /algorithm,dynamic link library.(dll) and software interface were developed by C++. Results Through comparing the ECG simulation results with clinical samples,the veracity and validity of the mathematical model/algorithm was verified. Conclusion The software module based on this model/algorithm is very valuable for ECG training and teaching in clinic,and can be implemented in the development of more advanced ECG relative software and devices.
