Abstract
BACKGROUND
The recent study of the variations of the origin of the sinoatrial node and on the "arterial network of the perinodal sinusal area" in normal hearts points out the importance of this network.
PURPOSE
Report on a case of patient with syncope of ischemic etiology.
CONCLUSION
In this patient the arterial network did not protect the node from the ischemia caused by the obstruction of the artery of the sinoatrial node.
摘要
背景
近期对正常心脏中窦房结起源变异及“窦周区域动脉网络”的研究指出了该网络的重要性。
目的
报告一例缺血性病因晕厥患者的病例。
结论
在该患者中，动脉网络未能保护窦房结免受窦房结动脉阻塞所致的缺血影响。
