The proportion of the left main, left anterior descending, left circumflex and right coronary artery that could be evaluated were 93.3%, 80%, 60% and 42.2%, respectively.
目的评价左冠状动脉回旋支急性闭塞超急期心电图特征及演变规律。
Objective To evaluate the character and variation of ECG during the acute phase of obliteration in circumflex branch of left coronary artery.
结果：17只猪中有16只猪术后存活8周以上，活体冠状动脉造影显示左冠状动脉回旋支均闭塞。
RESULTS: Totally 16 pigs of the 17 ones survived more than 8 weeks. Complete occlusion of left circumflex coronary artery was observed by coronary arteriography.
