One kind of method for obtaining and treatment of heart ECG

The present invention relates to a method for obtaining a heart rate and ECG signal processing method. The method comprises obtaining a heart rate on the recording time ECG waveform R-wave occurring; i-th time based on the time of the R wave appears TRi i-1 and the R wave appears times TRi-1, obtaining the instantaneous heart rate time TRi . The ECG signal processing method comprising: an input based on ECG, heart rate using the method for obtaining the heart rate acquired at time TRi; and, the heart rate during the processing time TRi. Aspect of the invention can obtain a heart rate more accurately reflect the true change in heart rate.
