atrioventricular node

基本解释

Conduction block. A block of your heart's electrical pathways can occur in or near the atrioventricular node, which lies on the pathway between your atria and your ventricles.
传导阻滞在心脏电脉冲的传导通路上，很多位置——比如在连接心房与心室的房室结附近，或是通向两个心室的通路（束支）上——都可能发生电信号的阻滞。
There is this specially adapted system of muscle and nerve tissue in the heart—the sinoatrial (SA) node, the atrioventricular node, and the Purkinje fibers—which sets the rhythm of the heart.
心脏中有一套由肌肉和神经组织构成的特殊体系，它们控制着心脏的节奏。这个体系由窦房结、房室结和浦金氏纤维（Purkinje fibers）组成。
It is characterized by sinoatrial node dysfunction and often includes atrioventricular node disease and bundle branch block.
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。
