摘要

我们报告了一例有症状的室上性心动过速患者，该患者在电生理学研究中没有 VA 传导。有趣的发现是，只有在特定周期长度的心室起搏时才出现 VA 传导，而这一周期长度可重复诱发持续的正交再发性心动过速（ORT）。我们回顾了相关文献并得出结论：超常 AP 传导可以解释这种现象。

“On-Off” phenomenon in a case of concealed left lateral atrio-ventricular accessory pathway - What is the mechanism?

We report a case of symptomatic supraventricular tachycardia who had absent VA conduction during electrophysiology study. The interesting finding was appearance of VA conduction only at a specific cycle length of ventricular pacing which reproducibly induced a sustained orthodromic re-entrant tachycardia (ORT). We review the literature and conclude that supernormal AP conduction can explain such phenomenon.
