Atrial dissociation is a very rare, transient arrhythmia frequently associated with intractable congestive heart failure. A case of atrial dissociation in a 48-year-old woman was observed in the first 72 hours of her recent inferolateral and probably atrial infarction. The slow unilateral rhythm was registered in the presence of sinus rhythm, 2:1 AV block, advanced AV block and ventricular pacemaker stimulation, respectively. The simultaneous right atrial electrogram indicated the origin of the isolated slow rhythm as left atrial. After temporary pacemaker therapy the atrial dissociation disappeared within three days; on the fifth day the normal sinus rhythm was restored spontaneously.
心房分离是一种非常罕见的短暂性心律失常，常与难治性充血性心力衰竭相关。在一名48岁女性近期下壁心肌梗死且可能合并心房梗死的最初72小时内，观察到一例心房分离病例。分别在存在窦性心律、2:1房室传导阻滞、高度房室传导阻滞和心室起搏器刺激的情况下记录到缓慢的单侧心律。同步右心房电图显示孤立性缓慢心律起源于左心房。经临时起搏器治疗后，心房分离在三天内消失；第五天窦性心律自发恢复。
