In a case of atrial flutter with a 9:2 atrioventricular response, the only possible way to explain the conduction pattern was 3:1 block in the atrioventicular node (which is 3:2 Wenckebach sequence in the N zone and a 2:1 block at the junction of the node with the bundle of His) plus 3:2 Wenckebach sequence distal to the H deflection. The recording of the His bundle deflection confirmed this analysis.
在一例房扑伴9:2房室传导反应的病例中，解释这种传导模式的唯一可能方式是房室结存在3:1阻滞（在N区为3:2文氏序列，在房室结与希氏束交界处为2:1阻滞），加上希氏束波（H波）远端的3:2文氏序列。希氏束波的记录证实了这一分析。
