心肌梗塞(MI)范围的大小是决定急性 MI 预后的一个主要因素。本文通过对急性 MI 患者2年的随访,观察心电图(EKG)Q 及 R 波改变与发病率的关系。方法:因初次透壁性 MI(464例)或心内膜下 MI(123例),于发病初三天内入冠心病监护病房的患者共587例,分为前壁 MI 与下壁 MI 二组。前壁 MI 患者计算入院四天内24个胸前标测导联的 R 波总和与 Q 波总和之差(ΣR-ΣQ),下壁MI 患者计算入院四天内Ⅱ、Ⅲ、aVF 导联的ΣR-ΣQ,并按最后的ΣR-ΣQ(mm)分为四组(如349～126,125～33.5,33.0～-60,-60～-187)进行比
The size of the myocardial infarction (MI) range is a major factor in determining the prognosis of acute MI. In this paper, the follow-up of 2-year follow-up of patients with acute MI was performed to observe the relationship between Q and R wave changes and incidence of electrocardiogram (EKG). METHODS: A total of 587 patients admitted to the coronary care unit at the first three days of onset due to initial transmural MI (464 cases) or subendocardial MI (123 cases) were divided into anterior MI and inferior MI . For patients with MI in the anterior MI, the difference between the sum of the R-wave and the Q-wave in the 24 precordial leads (ΣR-ΣQ) was calculated within 4 days after admission. The MI of the MI in the inferior MI was calculated as ΣR- ΣQ, and according to the final ΣR-ΣQ (mm) divided into four groups (such as 349 ~ 126, 125 ~ 33.5, 33.0 ~ -60, -60 ~ -187)
