Method and apparatus for detecting QRS complex of ECG

摘要

A method and apparatus for detecting the QRS complex an ECG signal comprises a first threshold computer (7) and a second threshold computer (5) receiving a preprocessed ECG signal (E5).;The first threshold value (T1) is based on a peak value of a QRS complex of the ECG signal (E5) and the second threshold value (T2) is derived from an average value (NA) of the ECG signal (E5). The first threshold value (T1) is compared with the second threshold value (T2), and the larger one of said threshold values (T1 and T2) is selected as a threshold value (T) for detecting the QRS complex. Synchronous signals (SYNC) are delivered in response to each detected QRS complex.
