对象为60.6±8.7岁的连续61(男45、女16)例急性心梗患者。24例前壁心梗,37例下壁心梗。29例接受溶栓治疗,其中19例获得成功。发病后第4天记录标准12导联心电图并作超声心动图检查。从QRS波起始部至T波结束处的时间,再按Bazett公式校正,计算QTc间期。左室分为13个节段,每段计分-1～+4(活动增强～室壁瘤形成),取总和。 全组的室壁活动计分同QTc间期正相 The subjects were 60 consecutive 61 (45 males, 16 females) with acute myocardial infarction (60.6 ± 8.7 years). 24 anterior myocardial infarction, 37 inferior myocardial infarction. Twenty-nine patients received thrombolysis, of which 19 were successful. On the fourth day after onset, a standard 12-lead electrocardiogram was recorded and examined by echocardiography. The time from the beginning of the QRS wave to the end of the T wave is then corrected by the Bazett equation to calculate the QTc interval. Left ventricle is divided into 13 segments, each score -1 ~ +4 (activity increased ~ aneurysm formation), take the sum. The whole group of wall activity score with QTc interval positive phase
