本文根据 Schlesinger 的分型法,观察了114例我国成人心脏,将冠状动脉分为右优势、左优势和均衡型三型,出现率分别为82.5%,9.6%和7.9%。著者认为与国外资料相比,国人心脏左优势的出现率明显偏低,而右优势则相对较高。统计了前降支的终止部位,多数终止于后纵沟的下1/3,其次为中1/3。这与解剖学教科书认为前降支多数终止于心尖不同。
According to Schlesinger’s classification, 114 adult Chinese adults were observed. The coronary arteries were divided into three types: right superiority, left superiority and balanced type. The incidence rates were 82.5%, 9.6% and 7.9% respectively. Author believes that compared with foreign information, the incidence of left heart superiority of Chinese people is obviously low, while the right advantage is relatively high. Statistics of the anterior descending branch of the termination site, the majority of the end of the longitudinal groove in the next 1/3, followed by 1/3. This is consistent with textbooks on anatomy that suggest that the majority of anterior descending branches terminate at the apex.
