Recognition of T waves in ECG signals

The method described in this paper deals with the problems of T-wave detection in ECG signals. Determining the position of a T-wave can be complicated, due to the ambiguous and changing form of the complex and the presence of noise. We developed a method to detect T-waves in noisy signals. The performance of the proposed method was tested on 33 records of the MIT/BIH arrhythmia database resulting in 0.48% incorrectly detected T waves.
