Research on ECG automatic analysis system based on virtual instrument

Electrocardiogram (ECG) is a biological signal which reflects the electronic excitement of cardiac activities and vital signs. As a kind of signal time marker, the parameter information of ECG, such as R wave amplitude and RR period, plays an important part in clinic. According to the traditional characteristics of ECG signal, an ECG automatic analysis system is designed based on virtual instruments. The system based on LabVIEW 2012, which is applied to analyze ECG signal real-time, also has the feature of high efficiency development and good flexibility. ECG signal can be analyzed automatically in this system and the feature point can be displayed at the same time.
