本文根据急性下后壁心梗累及右室可影响胸前导联T波的极性,分析研究了V_1导联T波极性与右或左旋冠脉病理解剖学的关系。 方法 80例初发急性下后壁心梗病人,男54例,女26例。症状发作5小时内冠脉造影发现右冠脉(RCK)闭塞。60例,左旋冠脉(LCK)闭塞19例,对照组100例。RCK病变组根据冠脉闭塞位置和V_1导联ST改变的方向,又分为4个亚组。27例近端RCK闭塞伴ST段抬高或等电位线为A_1组;7例近端闭塞伴ST段
In this paper, according to the acute inferior posterior wall myocardial infarction involving the right ventricle can affect the polarity of the chest wave T wave analysis of V 1 lead T wave polarity and right or left coronary artery pathological anatomy. Methods 80 cases of newly diagnosed acute posterior wall myocardial infarction patients, 54 males and 26 females. Coronary angiography within 5 hours of onset of symptoms revealed occlusion of the right coronary artery (RCK). 60 cases, left-sided coronary artery (LCK) occlusion in 19 cases, control group of 100 cases. According to the location of coronary occlusion and the direction of ST changes in V_1 lead, RCK lesions were divided into 4 subgroups. 27 cases of proximal RCK occlusion with ST elevation or equipotential line A_1 group; 7 cases of proximal occlusion with ST segment
