房间传导阻滞是指心房的房间束传导的延迟或阻滞。笔者阐明房间传导的解剖、生理机制 ,房间传导阻滞的诊断标准 ,明确其发病率较高 ,危害性是导致房性心律失常 (房性心动过速、心房颤动、心房扑动 )、左房扩大、血栓和血管栓塞。并探讨其治疗。双房起搏是目前治疗房间传导阻滞最有效的手段 ,为心脏起搏器治疗快速房性心律失常提供思路 Room block refers to the delay or block of atrial bundle conduction. The author states that the room conduction anatomy, physiological mechanisms, room conduction block diagnostic criteria, a clear high incidence, the risk is caused by atrial arrhythmia (atrial tachycardia, atrial fibrillation, atrial flutter), left atrial Enlargement, thrombosis and vascular embolism. And discuss its treatment. Biventricular pacing is currently the most effective means of treatment of room block, providing a guideline for pacemaker treatment of atrial tachyarrhythmia
