Two female patients, 54 and 38 years-old with refractory ventricular tachycardia were undertaken to electrophysiologic study for diagnosis and radiofrequency ablation of their arrhythmias. The tachycardias were only inducible with intravenous isoproterenol infusion. The site of the origin of ventricular tachycardia was localized in the right ventricular outflow tract in both cases. Radiofrequency current was delivered at 40V (40-60s) in each patient and was followed by complete abolition of ventricular arrhythmias.
两名分别为54岁和38岁的女性难治性室性心动过速患者接受了电生理研究，以诊断和射频消融其心律失常。室性心动过速仅在静脉输注异丙肾上腺素时可诱发。两例患者室性心动过速的起源部位均定位于右心室流出道。对每位患者在40V（40 - 60秒）下施加射频电流，随后室性心律失常完全消失。
