TpTe prolongation may flag proarrhythmic risk during EPS; hypothesis-generating, requires prospective validation before clinical adoption.
Does the TpTe interval reflect transmural dispersion of repolarization and serve as a pro-arrhythmic marker in patients undergoing electrophysiological study?
The TpTe interval on surface ECG likely represents transmural dispersion of repolarization and is greater in patients with inducible ventricular arrhythmias, suggesting its potential as a pro-arrhythmic marker.
