摘要

悖论反应的原因包括纯His捕获和不慎间歇性直接心房捕获。在指数病例中，我们推测悖论性延长的可能机制是由于房室结因 HH 间期缩短而减弱，而 HH 间期缩短的原因是在降速起搏输出过程中，在较宽的 Vc 搏动后出现了较窄的 H + Vc 搏动。

Paradoxical response during Para-Hisian pacing in a case with fasciculo-ventricular pathway: What is the mechanism?

Causes of paradoxical response include Pure His capture and inadvertent intermittent direct atrial capture. In the index case , we postulate that the likely mechanism of paradoxical prolongation could be due to decrement in the AV node due to the shortening of HH interval which happened as a result of a narrower H + Vc beat following a wider Vc beat during decremetal pacing output.
