本文对107例老年冠心病(CHD)患者的动态心电图监测(DCG),旨在进一步探讨无症状性心肌缺血(SMI)发生规律及预后,以便今后更好地防治。 1 临床资料 受检对象为1989年4月至1991年3月确诊为CHD的107例住院患者,男101例,女6例,年龄≥60岁,凡不能活动者及其它各种因素所致的ST段压低者均不在本研究之列。将受试者分为二组:Ⅰ组为单纯CHD组(14例),Ⅱ组为CHD伴糖尿病、高血压或(和)陈旧心梗组(93例)。二组平均年龄69.06±6.18岁。采用西德MQEIS 8000/T型双导盒式磁带记录器及分析仪,连续记录24h心电图,并进行计算机分析处理。凡J点后80ms ST段水平型或下斜型压低≥1.0mm,持续时间≥2min(随后回复至等电位线)为缺血性ST段压
In this paper, 107 patients with coronary heart disease (CHD) in patients with dynamic electrocardiogram monitoring (DCG), to further explore the rules and prognosis of asymptomatic myocardial ischemia (SMI), in order to better control in the future. 1 clinical data subject was diagnosed in April 1989 to March 1991 diagnosed as CHD in 107 cases of hospitalized patients, 101 males and 6 females, aged ≥ 60 years, who can not be caused by activities and other factors ST-segment depression are not in this study. The subjects were divided into two groups: group Ⅰ was simple CHD group (n = 14), group Ⅱ was CHD with diabetes mellitus, hypertension or old myocardial infarction group (n = 93). The average age of the two groups was 69.06 ± 6.18 years. West Germany MQEIS 8000 / T dual-lead cassette tape recorders and analyzers, 24h continuous recording of ECG, and computer analysis. Where the 80ms after J point ST-segment horizontal or down ramp pressure ≥ 1.0mm, duration ≥ 2min (then back to the equipotential line) for the ischemic ST segment pressure
