窦房传导阻滞简称窦房阻滞，系因窦房结周围组织病变，使窦房结发出的激动传出到达心房的时间延长或不能传出，导致心房心室停搏。窦房传导阻滞可暂时出现，也可持续存在或反复发作。窦房阻滞患者常无症状，也可有轻度心悸、乏力感以及“漏跳”，心脏听诊可发现心律不齐、心动过缓、“漏跳”（长间歇）。
它的特征是窦房结功能障碍并常伴有房室结疾病和束支传导阻滞。
It is characterized by sinoatrial node dysfunction and often includes atrioventricular node disease and bundle branch block.
将成为窦房结功能正常的房室传导阻滞患者的最佳选择。
It will be the best choice for atrioventricular block patients with normal sinus function.
结果窦性心律时窦房结发出冲动，激动右心房上部并向右心房下部和左心房传导，而房颤时双心房均可见方向不一、片段的激动波或大的折返环，可见多个传导阻滞区。
During acute AF, there are multiple and discrete excitation wave fronts or reentry activities were found in both LA and RA, and bidirectional block regions could be shown.
