title: Unusual site of origin of a non-automatic focal right ventricular tachycardia.
abstract: Focal right ventricular tachycardia is relatively uncommon. It usually arises from specific anatomic locations. A 59-year-old woman with a structurally normal heart and an automatic cardioverter-defibrillator implanted beforehand presented with drug-resistant incessant ventricular tachycardia for which 1786 anti-tachycardia pacing therapies and 119 shocks had been delivered. Electroanatomical mapping showed focal tachycardia originating from the acute margin of the right ventricle. Irrigated catheter ablation was performed successfully.
