Effects of Carvedilol on Suppressing the Premature Ventricular Complex/Ventricular Tachycardia From Outflow Tract

연구 개요

Carvedilol is known to be effective in reducing ventricular arrhythmias and mortality in patients with heart failure. It is suggested that one of the mechanisms is its ability to block store overload-induced Calcium release which activates spontaneous calcium release by Ryanodine receptors. Ventricular outflow tract tachyarrhythmia is known to be associated with calcium overload due to activation of Ryanodine receptors. The aim of this study is to evaluate the efficacy of Carvedilol on premature ventricular complex(PVC)/ventricular tachycardia(VT) originating from outflow tract.
