We report a case of an elderly man who presented to the emergency room complaining of palpitations. Electrocardiogram revealed wide QRS tachycardia with a narrow beat within the tachycardia. Most commonly, a narrow complex beat during a wide complex tachycardia suggests a capture or fusion beat in the setting of ventricular tachycardia. However, there are situations where supraventricular tachycardia can also manifest this way. In our patient a pacemaker interrogation clarified the diagnosis.
我们报告一例老年男性患者，其因心悸就诊于急诊室。心电图显示宽QRS心动过速，心动过速期间有一个窄波。在宽QRS心动过速期间出现窄波，最常见的情况是在室性心动过速背景下的夺获或融合波。然而，在某些情况下，室上性心动过速也可表现为这种形式。在我们的患者中，起搏器程控检查明确了诊断。
