Abstract: Background: Storm of short coupling PVT (SC PVT) is a rear clinical syndrome. Implantable cardioverter-defibrillator and radiofrequency ablation of arrhythmia trigger are optional for life threatening control and freedom from arrhythmia.
Method and Result: This case report describes a 50-year-old woman with normal repolarization duration who survived multiple electrical storms and cardiac arrest related to recurrent SC PVT. Betablocker and amiodarone suppressed storm of PVT and cardioverter defibrillator was implanted. After than radiofrequency ablation of premature ventricular contraction – trigger of PVT was performed.
Result: Radiofrequency ablation revealed high efficacy in long term prevention of recurrence of PVC triggering PVT and VF.
