本文42例均为老年人陈旧性心梗(以下称为 OMI),按梗塞部位不同分为下壁18例,下前壁5例,前壁5例,晚电位阳性检出率分别为22%,20%,20%,另外,前间壁6例,广泛前壁5例,正后壁2例,下后壁1例,均未能检出阳性晚电位。从观察结果分析:陈旧性心梗比急性期心梗晚电位阳性检出率低;下壁梗塞检出率高于其它部位梗塞。
In this paper, 42 elderly patients with obstructive myocardial infarction (hereinafter referred to as OMI), according to different infarct sites divided into 18 cases of inferior wall, 5 cases of anterior inferior wall, anterior wall in 5 cases, late potential positive rates were 22% , 20%, 20%. In addition, 6 cases of anterior wall, 5 cases of anterior wall, 2 posterior wall and 1 posterior wall failed to detect positive late potentials. From the observation results analysis: the old myocardial infarction than the acute phase of late detection of positive rate of myocardial infarction is low; the detection rate of inferior wall infarction is higher than other parts of the infarction.
