在通常所谓间歇性传导阻滞中,有相当一部份与心率变化有明显关系。在心率加快时出现传导阻滞,心率减慢时传导正常称为决心率依赖型传导阻滞(或3位相阻滞);而
In the so-called intermittent block, a considerable part of the change in heart rate has a clear relationship. Blocking occurs when the heart rate is accelerating, and when the heart rate is slowing down, conduction is normally called rate-dependent block (or phase 3 block); and
