作者采用简化的 Selvester(29分)记分法估价心肌梗塞范围对1969～1981年间经插管证实的非外科治疗的1915例冠心病者进行研究,以 Cox 相对危险因子模型评价 QRS 记分与存活机率的关系。本组患者年龄中位数为51岁,79%为男性,48%至少有1次心肌梗塞史。患者在插管前72小时内记录标准12导联心电图。QRS 记分的依据是R/Q、R/S 波幅比值和/或 Q、R 波时间。典型异常 Q波指除 aVR 外的任何一个导联 Q≥0.04秒。每个病例在插管后每年前瞻性地搜集有关症状、住院、心肌梗塞和死亡的资料。在1915例中有368例死于随访(1～13年)期间.全组1、3和5年的存活率分别为91%、82%和76%。作为单一因子,QRS 记分与插管后存活机率的关系具有显著性(p<0.0001).QRS
The authors used a simplified Selvester (29 points) scoring method to assess the extent of myocardial infarction in 1969 to 1981 confirmed by intubation of non-surgical treatment of 1915 cases of coronary heart disease were studied by Cox relative risk factor model to evaluate QRS score and survival probability relationship. The median age of our patients was 51 years, 79% were men and 48% had at least 1 history of myocardial infarction. Patients recorded a standard 12-lead electrocardiogram within 72 hours before intubation. QRS scores are based on R / Q, R / S amplitude ratio and / or Q, R wave time. Typical abnormal Q wave refers to any lead except aVR Q ≥ 0.04 seconds. In each case prospectively collect information on symptoms, hospitalizations, myocardial infarction, and death each year after intubation. Of the 1915 patients, 368 died during follow-up (from 1 to 13 years), with 1-, 3-, and 5-year survival rates of 91%, 82%, and 76%, respectively. As a single factor, the relationship between QRS score and survival after intubation was significant (p <0.0001) .QRS
