对700名就诊者分高血压、冠心病、其它疾病及青年体检组,以A和B两个标准分析三导动态心电图(DCG)对无症状心肌缺血(SMI)的诊断价值。(1)A标准:各组间ST下移或抬高次数无临床意义,其它疾病组的ST异常改变发生率达53.7％,假阳性率甚高;(2)B标准:心绞痛组缺血性ST改变的发生率为51.7％,而其它各组为9％～12.7％,前者ST缺血发作2.8h~(-1),而后者各组均≤1h~(-1)。B标准下DCG对SMI有一定价值但需结合临床。
The diagnostic value of three-point ambulatory electrocardiogram (DCG) for asymptomatic myocardial ischemia (SMI) was analyzed by A and B criteria in 700 outpatients with hypertension, coronary heart disease, other diseases and youth examination group. (1) A standard: ST down or elevation in each group was not clinically significant, the incidence of ST abnormal changes in other disease groups was 53.7%, the false positive rate is very high; (2) B standard: angina pectoris group The incidence of ST changes was 51.7%, while the other groups were 9% to 12.7%. The former had ischemic episodes of 2.8h ~ (-1), while the latter groups were all ≤1h ~ (-1). B standard DCG SMI have some value but need to combine clinical.
