【摘要】 <正> 关于心肌桥这一名称,首先由P.Polacek于1959年提出制订的。就是在心肌层表面,有时可见一处或数处的心肌纤维束跨过心冠状血管表面,其形似桥,故有心肌桥的命名。 1913年J.Tandler,1922年A.Crainicianu,1924年W.Spalteholz都曾先后更多还原

【Abstract】 1. The myocardial bridges on the coronaty arteries of 100 hearts were studied.These formations occur in 66.3±4.76% of the cases and were located as follows: (1) On the left coronary artery: 60.0±4.98% was found on the r. interventri-cularis ant.; 6.1±2.41% on the r. obliquus ventriculi sin.; 1.0±1.00% on the r. ter-minalis; 9.1±2.90% on the r. marginalis. (2) On the right coronary artery: 10.0±3.00% on the r. interventricularis post.;5.0±2.18% on the r. anteriores ventriculi dex.; 3.0±1.71% on the r. marginalis. (3) The rest: 3.1±1.76% on the v. cordis magna; 1.0±1.00% on the v. cordismedia. 2. Microscopic examination of 5 hearts showed that the myocardial bridge is a partof the superficial myocardial layer. 3. The result were discussed with those from other authors.更多还原
