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.
左冠状动脉主干、左前降支、左回旋支和右冠状动脉显示较好且能满足影像学评价分别占93.3%，80%，60%和42.2%。
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.
左冠状动脉主干钙化12例(27%)，左前降支近中段钙化有29例(64%)，左回旋支钙化例数22例(49%)，右冠状动脉近中段钙化有24例(53%)。
The calcium of coronary artery was in 12 cases (27%) of LM, left anterior descending 1, 2 (LAD1, 2) in 29 cases (64%), LCX in 22 cases (49%), right coronary artery 1, 2 (RCA1, 2) in 24 cases (53%).
结果冠状动脉狭窄发生率依次为前降支、右冠、回旋支及其他分支。
Results the stenosis of coronary artery occurred in left anterior descending most frequently, right coronary artery secondly, left circumflex thirdly and other branches.
陈旧性MI（OMI）组结扎冠状动脉左回旋支，无皮下置管；
OMI group, ligation of the circumflex coronary without subcutaneous polyethylene pipe;
罪犯血管为左前降支26例（66.7%），右冠状动脉5例（12.8%），左回旋支及钝缘支3例（7.7%），后降支5例（12.8%）。
The culprit vessel was left anterior descending in 26(66.7%), right coronary artery in 5(12.8%), circumflexobtuse marginal in 3(7.7%), and posterior descending in 5(128%).
结果在检查的1000例病人中380例（38%）有壁冠状动脉存在，其中314例发生在前降支及其分支，32例发生在回旋支及其分支，13例发生在右冠状动脉及其分支，另外21例为多支病变。
Results Parietal coronary arteriae were found in 380 patients, among them, 314 cases were at the LAD, 32 cases were at the CX, 13 cases were at the RCA and multiple arteriae involved in 21cases.
