Is a prolonged Tpeak-to-Tend interval on the resting ECG associated with an increased risk of sudden cardiac death?
Prolongation of the TpTe interval on resting ECG is an independent risk marker for sudden cardiac death, offering utility even when QTc cannot be used.
Prolongation of the TpTe interval measured in lead V5 was independently associated with SCD, with particular utility when the QTc was normal or not measurable because of prolonged QRSD.
