Electrophysiologic testing is known to be of value both diagnostically and in the evaluation of treatment modalities for patients with recurrent sustained ventricular tachycardia, out-of-hospital cardiac arrest, and syncope of unknown etiology. Attention is being focused on the possibility of identifying patients at high risk for such lethal ventricular arrhythmias in the hope that prophylactic therapy could prevent such arrhythmias from occurring. In this article, the authors discuss the potential role of electrophysiologic testing in this prospective identification and review the current data in the two groups of patients that have been studied extensively in this regard--post-myocardial infarction patients and patients with left ventricular dysfunction and congestive heart disease. The element of study artifact is also addressed.
已知电生理检查对于诊断以及评估复发性持续性室性心动过速、院外心脏骤停和病因不明的晕厥患者的治疗方式均具有价值。人们正将注意力集中在识别此类致命性室性心律失常高危患者的可能性上，期望预防性治疗能够防止此类心律失常的发生。在本文中，作者讨论了电生理检查在这种前瞻性识别中的潜在作用，并回顾了在这方面已进行广泛研究的两组患者——心肌梗死后患者以及左心室功能不全和充血性心脏病患者的现有数据。还讨论了研究假象的问题。
