摘要

方法和结果在短程 RP 室上性心动过速中，His 难复性室性早搏收缩（PVC）持续终止心动过速，且在 PVC 结束后未立即捕获心房。结论这些观察结果可诊断为慢速房室结复律性心动过速（AVNRT），并伴有旁观者隐匿性室性早搏，其原因可以用室性早搏本身的递减特性来解释；室性早搏的过早发生导致室性早搏的递减传导增加，从而导致 AVNRT 在一个周期后终止。

Decremental properties of a concealed nodoventricular pathway

IntroductionThe decremental properties of the nodoventricular pathway (NVP) are uncertain.Methods and ResultsDuring short RP supraventricular tachycardia, a His‐refractory premature ventricular contraction (PVC) consistently terminated the tachycardia without atrial capture immediately after the PVC. Whereas a slightly earlier PVC failed to reset the subsequent His but terminated the tachycardia without atrial capture one cycle later.ConclusionThese observations are diagnostic of slow‐fast atrioventricular nodal reentrant tachycardia (AVNRT) with a bystander concealed‐NVP and can be explained by decremental properties in the NVP itself; greater prematurity of the PVC resulted in more decremental conduction over the NVP, causing the AVNRT termination one cycle later.
