摘　　要：解剖１０５只成年家兔的心脏，测量冠状动脉左室支在左心耳下缘发出处到前室间沟距离，平均为７．２ｍｍ。另取３６只家兔随机分为：Ⅰ组左室支在左心耳缘下０～５ｍｍ、Ⅱ组５～７ｍｍ、Ⅲ组７～１０ｍｍ部位结扎．造成心肌缺血模型，结果表明，左室支结扎部位适宜在左室支距离左心耳缘下５～１０ｍｍ内，并探讨左室支分布与心脏重量相关关系和本模型特点．he distance between the origin of left ventricular branch (LVB ) of coromary artery and theanterior interventricular groove was measured as 7. 2±1.6mm in 105 adult rabbits, Thirty-sixrabbits were randomly divided into three groups:group 1 ligation of LVB 0～5mm distal to theorigin; grotip 2, ligation of LVB 5～7mm distal to the origin and group 3. lgation of LVB 7～10mm distally。 Acute myocardial ischemia experimeiital model was set up by arterial ligation。The suitable point of LVB ligation for the acute myocardial ischemia model was found within 5～10mm distal to the origin。 No correlationship was found between LVB distribtition and theweight of heart。
