Abstract

The "gap phenomenon" is an interesting phenomenon in electrophysiology arising from the differences in refractory periods at two or more levels of the atrioventricular (AV) conduction system. We present a patient with dual AV nodal physiology in whom the AH jump mediates the gap phenomenon. We also briefly discuss the other mechanisms of gap phenomenon that have been described in this setting.

摘要

“间隙现象”是电生理学中一种有趣的现象，它源于房室（AV）传导系统两个或更多水平的不应期差异。我们报告一例具有双房室结生理功能的患者，其中AH间期跳跃介导了间隙现象。我们还简要讨论了在此情况下已描述的间隙现象的其他机制。
