Abstract

We report a case of a 44-year-old male who underwent an electrophysiological study for symptomatic supraventricular tachycardia (SVT) with wide QRS complex. The SVT was diagnosed as an antidromic atrioventricular reentrant tachycardia (AVRT) via antegrade conduction of left-sided accessory pathway (AP). However, the QRS morphology changed during the SVT, and then the SVT was terminated spontaneously. The mapping of AP was performed during sinus rhythm, and the radiofrequency application successfully eliminated the AP, which rendered tachycardias non-inducible. This was a rare case of antidromic AVRT during which the QRS morphology changed.

反心动房室返流性心动过速时 QRS 形态的变化。

我们报告了一例 44 岁男性患者的病例，他因症状性室上性心动过速（SVT）伴宽 QRS 波群而接受了电生理检查。SVT 被诊断为通过左侧辅助通路（AP）逆行传导的反向房室返流性心动过速（AVRT）。然而，在 SVT 期间 QRS 形态发生了变化，随后 SVT 自动终止。在窦性心律时对 AP 进行映射，射频应用成功消除了 AP，从而使心动过速不再诱发。这是一例罕见的 QRS 形态发生变化的反心动过速（antidromic AVRT）病例。
