A 27-year-old white female with a history of paroxysmal supraventricular tachycardia presented to the emergency department complaining of intermittent palpitations. Although no tachydysrhythmia was present, she was noted to have two distinct PR intervals during normal sinus rhythm while in the emergency department. The patient was referred for electrophysiologic study. This study demonstrated dual AV nodal paths, and AV nodal reentrant tachycardia was induced and terminated. She was placed on flecainide for outpatient management of her dysrhythmia. Dual AV nodal pathways leading to AV nodal reentrant tachycardia is discussed.
一名有阵发性室上性心动过速病史的27岁白人女性因间歇性心悸前往急诊科就诊。尽管当时没有快速性心律失常，但在急诊科期间，她在正常窦性心律时被发现有两个不同的PR间期。该患者被转诊进行电生理检查。这项检查显示存在房室结双径路，并诱发和终止了房室结折返性心动过速。她被给予氟卡尼用于门诊治疗心律失常。文中讨论了导致房室结折返性心动过速的房室结双径路。
