Abstract

In this paper, a morphology based, time domain algorithm to detect QRS complexes in unfiltered ECG contaminated by 60Hz interference and baseline wandering is introduced. The method uses two slope trace waves which are the delayed version of an original signal with averaged slopes within a certain time interval. After the two slope trace waves are determined and used to remove 60Hz interference, another slope trace wave is followed to determine the epoch of QRS complexes by the help of amplitude and interval thresholds. The algorithm has been applied to ECG before preprocessing to show its practical applicability and efficiency. It is found that the method can detect the QRS complex appropriately in presence of 60Hz interference and baseline wandering.
