应用放射性核素对心前导联ST段压低的下壁心肌梗塞(MI)进行观察,现报道如下。一、病例选择40例下壁MI均经心电图和血清酶所证实,其中18例合并正后壁MI。男性34例,女性6例。年龄<40岁1例,41～50岁7例,51～60岁16例,61～70岁14例,>70岁2例。二、心电图表现将40例下壁MI分为两组;A组ST段压低组(简称压低组):在心前导联V_(?)～V_(?)至少同时有二个导联ST段压低≥1mm或在∑ST_v_1v_8v_(?)压低
Application of radionuclide on the ST segment depression of the anterior myocardial infarction (MI) were observed, are reported below. First, the case selection 40 cases of inferior MI were confirmed by ECG and serum enzymes, of which 18 cases were combined with posterior wall MI. 34 males and 6 females. 1 patient aged <40 years, 7 patients 41 to 50 years old, 16 patients 51 to 60 years old, 14 patients 61 to 70 years old and 2 patients> 70 years old. Second, the ECG showed 40 cases of inferior MI were divided into two groups; A ST-segment depression group (referred to as the depression group): in the precordial leads V_ (?) ~ V_ (?) At least two leads at the same time ST-segment depression ≥ 1mm or lower in ΣST_v_1v_8v_ (?)
