摘要(Abstract)：
目的 了解冠状动脉(冠脉)造影下窦房结动脉(sinusnodeartery ,SNA)的形态与起源,明确窦房结动脉相关病变与病态窦房结综合征(sicksinussyndrome ,SSS)的关系。方法 连续观察51 1人的冠脉造影资料,比较有无窦房结动脉相关病变的两组各2 9人的心率和SSS发病情况,以及有无SSS和(或)窦性心动过缓的两组各34人的窦房结动脉相关病变情况。数据采用SPSS1 0 0软件包进行统计分析处理。结果 51 1人中观察到50 6人的窦房结动脉共56 1支,其中53人( 1 0 . 1 7% )有双SNA ,1人有三支SNA。右、左和后窦房结动脉分别为2 75支( 4 9. 0 2 % )、2 0 5支( 36 . 54% )和81支( 1 4 . 4 4% )。有无窦房结动脉相关病变的两组平均心率( 71 . 59±7 .4 5次 分vs 73 .76±6 . 6 7次 分)及患SSS患者数量( 1人vs 0人)的差异无统计学意义(P >0 0 5)。SSS组和非SSS组窦房结动脉受累情况(SSS组34人有2人狭窄4 0 %和90 % ,非SSS组34人有2人狭窄4 5%和2 0 % )的差异无统计学意义(P >0 .0 5)。结论 冠脉造影下基本可以清晰地看到窦房结动脉。窦房结动脉相关病变与SSS关系不大。
