QRS complex detection by the combination of maxima and zero-crossing points of wavelet transform

The proposed algorithm uses the wavelet transform (WT) to detect the QRS complex of an electrocardiogram (ECG). Compared to other algorithms, which only use WT zero-crossing points, this algorithm detects the ECG characteristic points by a combination of the maxima and the zero-crossings of the WT. This algorithm can easily distinguish the QRS complex by comparison with prior work. The detection method and results are presented.
