摘要

双向室性心动过速（BDVT）是一种罕见的心电图发现，其特征是快速、宽复杂、交替的QRS形态，在额平面轴上有180度摆动，或者，不太常见的是，交替的右束支和左束支传导阻滞形态。BDVT的最新机制涉及钙失调引起的活动触发或自律性增强。儿茶酚胺激增可导致心肌损伤以及钙失调，导致自律性增强，从而导致心律失常，如BDVT。本病例报告描述了BDVT和应激性心肌病的独特表现，这是由在使用甲基苯丙胺的情况下多处创伤性枪伤后儿茶酚胺激增引起的。

Bidirectional Ventricular Tachycardia with Stress-Induced Cardiomyopathy

Bidirectional ventricular tachycardia (BDVT) is a rare electrocardiographic finding characterized by rapid, wide complex, alternating QRS morphology with 180-degree swings in the frontal plane axis or, less commonly, alternating right bundle branch and left bundle branch block morphology. The most proposed mechanisms for BDVT involve triggered activity or enhanced automaticity resulting from calcium dysregulation. Catecholamine surge can cause myocardial injury as well as calcium dysregulation resulting in enhanced automaticity that can lead to arrhythmias such as BDVT. This case report stands to describe a unique presentation of BDVT and stress-induced cardiomyopathy, resulting from catecholamine surge following multiple traumatic gunshot wounds in the setting of methamphetamine use.
