摘要

2:1 房室（AV）传导阻滞可发生在传导系统的任何部位，无创测量不一定能准确预测阻滞部位。虽然阻滞的定位对于决定任何治疗都至关重要，但也应仔细询问患者在休息和劳累时的症状。本文报告了一例 2:1 房室传导阻滞患者，该患者仅在用力时出现症状，非侵入性诊断方法显示其为结内阻滞，但在电生理研究中发现其为结内阻滞。

A long-standing conundrum: an unusual case of 2:1 atrioventricular block with conflicting findings.

A 2:1 atrioventricular (AV) block can occur anywhere within the conduction system, and noninvasive measurements may not always predict the exact site of the block. Although localization of the block is critical for deciding any treatment, patients should also be carefully questioned about symptoms both at rest and during exertion. A case of 2:1 AV block that was symptomatic only during exertion, appeared infranodal by noninvasive diagnostic methods, but was found to be intranodal on electrophysiological study is reported.
