Tpeak-Tend indices provide additional predictive value for identifying high-risk individuals for adverse outcomes in patients with acquired QT prolongation.
Do prolonged Tpeak-Tend intervals and higher Tpeak-Tend/QT ratios predict ventricular arrhythmias or sudden cardiac death in patients with acquired QT prolongation?
Tpeak-Tend interval and Tpeak-Tend/QT ratio are significantly elevated in patients with acquired QT prolongation who develop torsade de pointes, suggesting their utility as non-invasive risk stratification markers.
Absolute Event Rate: 0% vs 0%
compared to those who did not. These repolarization indices may provide additional predictive value for identifying high-risk individuals.
