Abstract：
Para-Hisian pacing (PHP) is among the most useful maneuvers in cardiac electrophysiology during sinus rhythm and identifies whether retrograde conduction is dependent on the atrioventricular (AV) node. 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. A common misconception about PHP is that it is useful only for septal accessory pathways (APs). However, even with left or right lateral pathways, as long as pacing from the para-Hisian region conducts to the atrium with the activation sequence being analyzed, it can be used to determine whether that activation is AV node-dependent or AP-dependent.
摘要：
Para-Hisian起搏（PHP）是窦性心律期间心脏电生理学中最有用的动作之一，可确定逆行传导是否取决于房室（AV）结。在这次演习中,在His束捕获和丢失捕获过程中,比较了逆行激活时间和模式,同时从对Hisian位置起搏。关于PHP的一个常见误解是它仅对间隔附件路径（AP）有用。然而,即使有左或右横向通路，只要在分析激活序列的情况下，从副希斯亚区域向心房进行起搏，它可以用于确定该激活是依赖于AV节点还是依赖于AP。
