Detection of Discontinuity in ECG Using Wavelet Transform

The Wavelet transform has emerged over recent years as a key time frequency analysis and coding tool for the Electrocardiogram (ECG). Its ability to separate out pertinent signal components has led to a number of wavelet based techniques which supersede those based on traditional Fourier methods. It is interesting to note that researchers in the field of Wavelet transform tend to take an approach to their study by either concentrating on the discrete Wavelet transform or the continuous Wavelet transform but relatively a few explore both in depth. Efficacy of Wavelet transform in highlighting small perturbations in an ECG which are not visible to the naked eye is presented in this paper using both CWT and DWT. On the other hand a new mother wavelet is presented for exclusive ECG analysis.
