Abstract

The purpose of this paper is introduction to the area of ECG signal analysis focused on T-wave alternans detection. In order to proceed with estimation of the T-wave alternans, a multi-stage preliminary signal preparation is necessary. Successive stages, illustrated in the paper, are: filtration, heartbeat segmentation, R and T wave searching and final signal evaluation. In the paper authors propose a novel method for ECG signal evaluation in order to proceed with T-wave alternans (TWA) estimation.
