本文就我科近5年来收住院的42例急性下壁心肌梗塞(AIMI)患者,均为删除心室肥厚、预激综合征、洋地黄中毒等影响ST段的病例。根据其胸前导联是否有ST段下降分为两组:≥1mm为A组(20例);<1mm为B组(22例),二组间的年龄、性别和发病时间经X~2检验P>0.1,具有可比性。应用多项指标进行客观评价。结果 (1)血清GOT、LDH,CPK峰值见附表。(2)心电图QRS记分法:采用Weger简化后的标准进行记分,A、B二组分别为5.2±1.67和3.3±1.61(P<0.01)。(3)心力衰竭:指Killip临床分级法Ⅲ级以上者,A组11例(55％);B组4例(18.2％),两者相比P<0.05。(4)严重心律失常:指Ⅱ度以上房室传导
In this paper, we collected 42 cases of acute inferior myocardial infarction (AIMI) admitted to our hospital in the past five years, all of whom were patients with ST-segment loss of ventricular hypertrophy, Wolff-Parkinson-White syndrome and digitalis poisoning. According to whether there is a ST-segment decrease in the chest lead, the patients were divided into two groups: ≥1mm for group A (20 cases); <1mm for group B (22 cases). The age, sex, Test P> 0.1, comparable. Use a number of indicators for objective evaluation. Results (1) Serum GOT, LDH, CPK peak see Schedule. (2) Electrocardiogram QRS scoring method: The Weger simplified criteria were used for scoring. The two groups were 5.2 ± 1.67 and 3.3 ± 1.61, respectively (P <0.01). (3) Heart failure: refers to the Killip clinical grade Ⅲ or more, 11 cases (55%) in group A; 4 cases (18.2%) in group B, P <0.05. (4) severe arrhythmia: refers to more than a degree of atrioventricular conduction
