WebThe calculation of the T-wave amplitude in the ECG is important for clinicians and it is a challenging task in noisy scenarios (e.g. microvolt T-Wave alternans detection). We can improve the T-wave amplitude estimates by tracking it over the noisy ECG segments and calculating it from the estimates provided by the method we proposed in this paper.
