A patient with coarse atrial fibrillation and a rapid ventricular response developed periods of high grade atrioventricular block interpersed with periods of rapid ventricular conduction after the administration of digitalis and propranolol. Intracardiac atrial recordings showed similar atrial rhythms of high right atrial flutter and left atrial fibrillation. The low right atrial recordings showed flutter during the periods of fast ventricular rates and fibrillation during periods of slower ventricular rates.
一名患有粗大型心房颤动且心室率快速的患者，在使用洋地黄和普萘洛尔后，出现了高度房室传导阻滞期，其间穿插着快速心室传导期。心内心房记录显示右心房上部扑动和左心房颤动的心房节律相似。右心房下部记录显示，心室率快时为扑动，心室率慢时为颤动。
