Original Abstract

In this paper, we present a simple T wave end detection algorithm based on a continuous wavelet transform. We used this algorithm to test, which prototype wavelets are optimal for the T wave end detection. Several prototype wavelets were tested on four different T wave morphologies in a chosen wavelet transform scale range. The result of this study is, that efficient prototype wavelets are bior1.1, bior1.3, bior1.5 and gaus1. Another conclusion is, that biorthogonal wavelets are less sensitive to a scale selection, so an algorithm based on a biorthogonal wavelet is more robust, than an algorithm based on a Gaussian derivative wavelet.
