Abstract
An electrical storm is defined as multiple occurrences of ventricular tachycardia/fibrillation (VT/VF) within a single day; this is a medical emergency and a poor prognostic marker in patients with an implantable cardioverter-defibrillator (ICD). We report here on the occurrence of electrical storms in a 35-year-old man with a repaired DCRV and ICD. He had recurrent VT and electrical storms that were refractory to amiodarone and ¥â-blocker. A cardiac electrophysiologic study was performed 11 months after the ICD was implanted and two forms of VT were induced. After the catheter ablation of the VTs, the monomorphic VT became non-inducible. The frequency of the VT decreased from 35 per month before the catheter ablation to 1.1 times per month after the procedure. Catheter ablation of VT could be an effective treatment for patients with electrical storms refractory to antiarrhythmic drugs.
