Repolarization parameters and ventricular arrhythmias in Takotsubo syndrome: A substudy from the RETAKO national registry

Inquiries about Tpe and ventricular arrhythmias in patients with takotsubo syndrome

“…Vazirani and colleagues 1 reported on the advantages of the employment of the T-wave peak–end (Tpe) interval uncorrected and corrected for heart rate, over the traditional QT interval corrected for heart rate, using Bazett’s formula, as a predictor of ventricular arrhythmias (VAs) (monomorphic and polymorphic ventricular tachycardia and ventricular fibrillation) in patients with takotsubo syndrome (TTS), based on the data from the RETAKO (REgistro nacional multicéntrico sobre síndrome de TAKOtsubo) registry. The authors also found that the precordial lead–derived longest Tpe may be an easier and more reliable marker than the QT interval corrected for heart rate, for the prediction of VAs in TTS.…”
