Electrical storm in an infant with short-coupled variant of torsade de pointes.


ABSTRACT: A 10-month-old infant experienced cardiac arrest caused by ventricular fibrillation (VF). His electrocardiogram (ECG) at rest was within the normal range. Amiodarone was indispensable due to its refractoriness to defibrillation. After implantable cardioverter defibrillator (ICD) implantation, ICD shock was delivered. ICD recordings documented VF and ventricular tachycardia (VT) triggered by premature ventricular contractions with an extremely short coupling interval (240 ms), which were controlled by verapamil. To the best of our knowledge, our case is the first infant with ScTdP. As the electrical storm with ScTdP occurs unpredictably, it can be a cause of sudden infant death syndrome.
