Fetal Cardiac Repolarization Abnormalities
The American Journal of Cardiology, 2006Abnormal cardiac repolarization renders the heart susceptible to lethal ventricular tachyarrhythmias, increasing the risk of sudden cardiac death in all ages; however, little is known about the incidence and etiology of T-wave abnormalities in utero. In this study, magnetocardiography was used to better define fetal T-wave characteristics, including ...

Assessing repolarization: Alternate hypotheses
Heart Rhythm, 2012c t r b ( p Sudden cardiac arrest remains a leading cause of death, the underlying cause typically being ventricular tachycardia or ventricular fibrillation (VT/VF). The mechanism for VT/VF is thought to be reentry in most cases, but our inadequate understanding of how reentry is initiated hampers our ability both to identify those at greatest risk and

Impaired Ventricular Repolarization Dynamics in Patients with Early Repolarization Syndrome
Journal of Cardiovascular Electrophysiology, 2013QT Dynamics in Early Repolarization SyndromeIntroductionAlmost all current investigations on early repolarization syndrome (ERS) have focused on the J‐wave characteristics and ST‐segment configuration; however, few have reported on ventricular repolarization indexes in ERS.Methods and ResultsA total of 145 subjects were enrolled: 10 ERS patients, 45 ...

The early repolarization syndrome
The Journal of Emergency Medicine, 1989The syndrome of the early repolarization variant is described. This benign ECG phenomenon is noted in 1% to 2% of the adult population and generally occurs in the absence of myocardial disease. The ECG manifestations may mimic acute myocardial injury or pericarditis. Exercise and isoproterenol tend to normalize the RST segment elevation.

Ventricular repolarisation is the period that depolarised cells require to become polarised, that is to say excitable. In general cardiological practice, the duration of repolarisation is assessed by measuring the QT interval on the surface electrocardiogram.
