{Reference Type}: Case Reports {Title}: A case of short QT-interval postventricular arrhythmia arrest from Torsade De Pointes, a new phenotype, or the result of tachycardia-mediated imbalance. {Author}: Ifedili I;Maturana M;Kayali S;Levine Y;Kabra R;Jha SK; {Journal}: J Cardiovasc Electrophysiol {Volume}: 35 {Issue}: 3 {Year}: 2024 Mar 4 {Factor}: 2.942 {DOI}: 10.1111/jce.16164 {Abstract}: BACKGROUND: We 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.
RESULTS: A 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.
CONCLUSIONS: A transient, potentially artificial, short QT interval following Torsades de Pointes can occur in patients with LQTS.
