引言：窦性心律期间的帕拉-希氏起搏有助于识别是否存在旁路（AP）。在该操作中，从希氏束帕拉位置起搏时，比较希氏束夺获和失夺获期间的逆行激动时间和模式。然而，逆行性AP的识别并不需要在感兴趣的心动过速期间有效;相反，缓慢传导或“远端”旁路可能无法识别。我们评价了从希氏帕拉位进行心动过速的牵拉或重置以帮助区分房室结折返性心动过速（AVNRT）和顺向性房室心动过速（AVRT）的效用。
Introduction: Para‐Hisian pacing during sinus rhythm can help to identify the presence of an accessory pathway (AP). In this maneuver, the retrograde activation time and pattern are compared during capture and loss‐of‐capture of the His bundle while pacing from a para‐Hisian position. However, identification of a retrograde AP does not necessitate that it is operative during the tachycardia of interest; conversely, slowly conducting or “distant” bypass tracts may not be identified. We evaluated the utility of entrainment or resetting of tachycardias from the para‐Hisian position to help distinguish atrioventricular nodal reentrant tachycardia (AVNRT) from orthodromic atrioventricular tachycardia (AVRT).
