Following exercise testing, a 71-year-old man developed atrial tachycardia with a unusual form of conduction disturbance: 4:2 atrioventricular (A-V) block. This pattern of A-V block is explainable by two different mechanisms of concealed conduction: two different levels of block in the A-V nodal region and dual A-V nodal pathways with concealed retrograde conduction of P waves. These concepts can also explain a variety of other unusual conduction disturbances.
运动试验后，一名71岁男性出现房性心动过速，并伴有一种不寻常的传导障碍形式：4:2房室传导阻滞。这种房室传导阻滞模式可通过两种不同的隐匿性传导机制来解释：房室结区域存在两个不同水平的阻滞以及具有P波隐匿性逆行传导的双房室结径路。这些概念也可以解释多种其他不寻常的传导障碍。
