The syndrome of sudden cardiac death, which claims the lives of hundreds of thousands of Americans each year, is usually caused by ventricular tachycardia or fibrillation. Electrophysiologic testing is now being used to prevent recurrence of this syndrome in successfully resuscitated persons. With this procedure, antiarrhythmic drugs are assessed in terms of their ability to prevent induction of sustained ventricular tachyarrhythmias, rather than their ability to merely suppress ventricular premature beats. In medically unresponsive patients, an automatic cardioverter-defibrillator can be implanted to provide maximal protection from sudden cardiac death caused by ventricular tachyarrhythmias.
心脏性猝死综合征每年夺去成千上万美国人的生命，通常由室性心动过速或心室颤动引起。目前，电生理检查正被用于预防成功复苏的患者再次出现该综合征。通过这种检查程序，可以评估抗心律失常药物预防持续性室性快速心律失常诱发的能力，而不仅仅是其抑制室性早搏的能力。对于药物治疗无效的患者，可以植入自动心脏复律除颤器，以最大程度地预防由室性快速心律失常引起的心脏性猝死。
