Characteristics of idiopathic ventricular tachycardia originating above the pulmonary valve

Panoptic studies of ventricular tachycardia (VT) originating above the pulmonary valve are scarce. The purpose of this study is to clarify the characteristic of idiopathic VT arising above pulmonary valve. We analyzed 15 consecutive patients with idiopathic VT that was successfully abolished by cath...

Description
Summary:Panoptic studies of ventricular tachycardia (VT) originating above the pulmonary valve are scarce. The purpose of this study is to clarify the characteristic of idiopathic VT arising above pulmonary valve. We analyzed 15 consecutive patients with idiopathic VT that was successfully abolished by catheter ablation at the right ventricular outflow tract (RVOT-VT, n  = 11) and above the pulmonary valve (PA-VT, n  = 4). Incidence of syncope was higher in PA-VT than RVOT-VT (100 vs 27 %, P
