Abstract
The predictive value of various ECG repolarization markers for the emergence of VA in patients with TTS was reviewed. The literature reports on QT, more recently on Tpe, and rarely on some more QT-derived metrics, revealing a contribution of these variables for the prediction of VA, complicating the acute, subacute, and follow-up clinical trajectory of patients with TTS. More recent literature reveals that Tpe and some other QT-based metrics, have outperformed the traditionally employed QT marker, although certainty about this awaits confirmation by future carefully designed and implemented studies.
