摘　　要：本文探讨了心绞痛患者治疗后高频心电图变化,10例经治疗后症状消失,动态心电图缺血性改变消失,12导联切迹数减少3.2个,治疗前后比较有显著差异。7例症状有改善,动态心电图显示有心肌缺血者,12导联切迹数减少1.9个,治疗前后比较无明显差异。说明高频心电图可以作为判断心绞痛治疗效果的指标。Many studies have proved that increment of high frequency compounts exists in coronary heart disease (CHD). High-frequency ECG (HFECG) is more sensitive to mycardial ischemia than standard ECG. In this report, changes of HFECG in angina pestoris (AP) after treatment was investigated. 17 patients with AP,there were ST-T depress in 24-hour Holler HFECG when AP occurred, entered into the study. Before treatment, HFECG was examined in all 17 patients. After treatment, 10 patients without any symptom and ST-T depress in holler ECG were divided into group A, another 7 patienls with symptom decrement and ST-T depression holler ECG were divided inlo group B. Before treat ment, there were 9.313.4 notches in 12 leads HFECG in group A and 11.6±4.8 notches in group B, respectively (P>0.05). After treatmenl, nolches decreased by 3.2 in group A (compared to before Ihrealmenl, P<0.05) and 1.6 in group B (compared to before treatment, P>0.05), respectively, notches decreased more in group A than in group B (P<0.05). The resulls indicated that (1) nolches would decrease in HFECG with treatment in AP. (2) changes of HFECG notches can serve as an index to identify treatmen tresult in CAD. Because the sample is small, further study is needed.
