Abstract
Ventricular tachycardia is a well-known complication in patients with hypertrophic cardiomyopathy. We report the case of a patient with hypertrophic cardiomyopathy with easily inducible monomorphic ventricular tachycardia. Electrophysiology study demonstrated that bundle branch reentry was the mechanism of the tachycardia. The tachycardia was rendered non-inducible by radiofrequency ablation of the right bundle branch.
摘要
室性心动过速是肥厚型心肌病患者中一种众所周知的并发症。我们报告一例肥厚型心肌病患者，其单形性室性心动过速易于诱发。电生理研究表明，束支折返是心动过速的机制。通过射频消融右束支，使心动过速不能被诱发。
