近十年对急性心肌梗塞早期阶段不可逆心肌细胞损害的决定因素注意颇多,而关于梗塞后期,包括心肌梗塞疤痕形成的决定因素,则了解甚少,尤其对早期运动是否影响心肌梗塞的疤痕形成和局部解剖构成尚不清楚。本文研究心肌梗塞尚未愈合期进行运动对其疤痕形成的影响。方法:22只体重350～450克 Sprague-Davi-ley 大鼠开胸在肺动脉流出道与左房之间作左冠状动脉结扎术。术后6天,18只存活大鼠在浅乙醚麻醉下作心电图检查,记录标准肢导联及胸前导联V_1、V_2、V_4、V_6,测定胸前导联病理性 Q 波幅度的总
In the last decade attention was paid to the determinants of irreversible cardiomyocyte damage in the early stages of acute myocardial infarction, and little is known about the determinants of post infarction, including the formation of myocardial infarction scarring, especially whether early exercise affects scarring of myocardial infarction And local anatomy is not yet clear. This article studies the effect of exercise on the scar formation in patients with myocardial infarction that has not yet been healed. Methods: Twenty-two Sprague-Davi-ley rats, weighing 350-450 g, underwent thoracotomy for the left coronary artery between the pulmonary artery outflow tract and the left atrium. Six days after operation, 18 surviving rats under light anesthesia with ether were examined by electrocardiogram. V_1, V_2, V_4 and V_6 of the lead of the limbs and the precordial leads were recorded.
