A noise independent approach to QRS-complex detection using CWT

In this paper we propose an efficient approach to QRS-complex detection using the Continuous Wavelet Transform (CWT). The method described in this paper is not affected by the presence of noise in the ECG signal nor does it depend on the morphology of the ECG waves. The speed of analysis of ECG signals using CWT and the accuracy of QRS-complex detection has been increased. The implementation of this method puts the CWT based peak detection methods at par with the DWT based methods with, same and in some cases, better accuracy of detection than the DWT based methods.
