Tachycardia with a wide QRS complex is usually due to ventricular tachycardia (VT), supraventricular tachycardia (SVT) with aberrant intraventricular conduction, or an accessory pathway-mediated dysrhythmia. The most common type of accessory pathway causing a wide complex tachycardia is the atrioventricular bypass tract. Distinguishing the accessory pathway-mediated tachycardia from VT or SVT with aberrancy is often difficult, but has important clinical consequences. This article will review the diagnosis of wide complex tachycardia due to an accessory pathway and its related management in the emergent setting.
宽QRS波心动过速通常由室性心动过速（VT）、伴有室内差异性传导的室上性心动过速（SVT）或旁路介导的心律失常引起。导致宽QRS波心动过速最常见的旁路类型是房室旁路。区分旁路介导的心动过速与伴有差异性传导的室性心动过速或室上性心动过速往往很困难，但具有重要的临床意义。本文将综述急诊情况下由旁路引起的宽QRS波心动过速的诊断及其相关处理。
