The T wave is the most labile wave in the electrocardiogram (ECG). The method (independent sub-band function) described in this paper deals with the problems of T- wave detection in an ECG. Determining the position of a T-wave is complicated due to the low amplitude, the ambiguous and changing form of the complexes. Independent sub-band function handles these complications therefore a method based on blind source separation (BSS) was developed. In this way we developed a detection method that is able to detect T-waves with a correct-detection ratio of 93% even with a serious amount of baseline drift and noise. The proposed algorithms perform better as compared with published results of other T-wave detectors tested on the same ECG data.
