Should T-wave alternans magnitude be corrected with T-wave amplitude in the ultra-short-term prediction of life-threatening cardiac arrhythmias?

We appreciate efforts by Dr Madias to develop T-wave alternans (TWA) index based on the theory that TWA magnitude is affected by T-wave amplitude and should, therefore, be corrected.1 He suggested that there may be limitations in correlating TWA magnitude data derived from the J-point to the end of the T-wave with the corresponding peak of the T-wave.2 We could not measure the area under the ECG curve from the J-point to …
