Are ventricular repolarization markers effective in predicting malignant arrhythmias in various clinical conditions?
Ventricular repolarization markers from standard 12-lead ECGs show promise for risk stratification of malignant arrhythmias across various clinical conditions, though consensus is still lacking.
Yaniel Castro Torres (2015) conducted a review in Malignant cardiac arrhythmias. Ventricular repolarization markers (corrected QT, QT dispersion, Tpeak-Tend, Tpeak-Tend dispersion, Tp-e/QT) was evaluated. Ventricular repolarization markers from 12-lead ECGs, such as corrected QT and Tp-e/QT, have demonstrated utility in predicting malignant arrhythmias across various clinical conditions.
