Abstract
An electrocardiograph (ECG) signal processing method and apparatus to resolve a problem that relatively severe interference caused during single-arm measurement for single-lead ECG collection seriously affects accuracy of heart rate calculation and cardiac rhythm analysis. The method includes collecting, by a measurement device, an ECG signal, extracting a kvalid QRS complex of the ECG signal, calculating a ktime difference and a (k+1)time difference, and determining whether the ktime difference and the (k+1)time difference are target time differences. In this way, accuracy of ECG feature extraction is improved, the interference caused during the single-arm measurement is eliminated to the most extent, and the accuracy of heart rate calculation and cardiac rhythm analysis can be effectively guaranteed.
