This is a serial section examination of the conduction system of five hearts of various types of dextrocardia. In one case of dextroversion the conduction system was found to be normal. In one case of mirror-image dextrocardia the conduction system was normal but in the opposite spatial position. In one heart of mixed (discordant) dextrocardia, the sinoatrial node was in correct morphologic position. There were two atrioventricular nodes - a posterior node close to the coronary sinus and an anterior node in the roof of the morphologic right atrium. They formed two separate bundles which joined in the left ventricle to form a "sling". In two cases of presumptive mirror-image dextrocardia, with a common atrium in situs inversus according to the morphology of the atrial appendages, with common atrioventricular orifice (CAVO), the sinoatrial node was situated in wrong positions. Two atrioventricular nodes and bundles again formed a sling. There are various types of slings in discordant dextrocardia.
这是对五例不同类型右位心心脏传导系统的连续切片检查。在一例右心转位病例中，发现传导系统正常。在一例镜像右位心病例中，传导系统正常，但处于相反的空间位置。在一例混合型（不一致型）右位心的心脏中，窦房结处于正确的形态学位置。有两个房室结——一个靠近冠状窦的后结和一个位于形态学右心房顶部的前结。它们形成两个独立的束，在左心室汇合形成一个“吊带”。在两例推测为镜像右位心的病例中，根据心耳形态，心房呈反位，有共同房室口（CAVO），窦房结位于错误位置。两个房室结和束再次形成一个吊带。在不一致型右位心中有各种类型的吊带。
