A case of short QT‐interval postventricular arrhythmia arrest from Torsade De Pointes, a new phenotype, or the result of tachycardia‐mediated imbalance

Physiology (medical)
Cardiology and Cardiovascular Medicine

AbstractIntroductionWe report the case of an 18‐year‐old female with recurrent syncope that was discovered to have congenital long QT syndrome (LQTS) and episodes of a transiently short QT interval after spontaneous termination of polymorphic ventricular tachycardia.Methods & ResultsA cardiac event monitor revealed a long QT interval and initiation of polymorphic ventricular tachycardia by a premature ventricular complex on the preceding T‐wave. After 1 minute of ventricular fibrillation, her arrhythmia spontaneously terminated with evidence of a short QT interval.ConclusionsA transient, potentially artificial, short QT interval following Torsades de Pointes can occur in patients with LQTS.
