Benchmarking of a T-Wave Alternans detection method based on empirical mode decomposition

The phenomenon of T –wave alternans (TWA), which is found on the surface electrocardiogram (ECG) as a periodic pattern given on an every–other–beat basis, is referred to the subtle variations of amplitude, waveform, and duration of the ST–T complex. Also named repolarization alternans, it has been found to be a clinical method to identify patients at risk for malignant arrhythmias and also as a marker for stratifying risk of sudden cardiac death (SCD) [1–3]. From a theoretical point of view, the problem statement for its characterization is easy and well defined, as it basically consists of finding a p eriodic pattern.
