摘要
目的:研究24 h动态心电图在冠心病心肌缺血、心律失常、心绞痛中的诊断价值。方法:127例临床诊断冠心病的门诊和住院患者,均进行24 h动态心电图及常规心电图检查;比较两组心肌缺血、心律失常、心绞痛的检出情况。结果:动态组心肌缺血阳性检出率(90.55%)显著高于常规组(34.65%),差异具有统计学意义(P<0.05)。动态组各类心律失常检出率显著高于常规组(P<0.05)。动态组检出变异性心绞痛16例,常规心电图未发现,差异具有统计学意义(P<0.05)。结论:24 h动态心电图诊断冠心病心肌缺血、心律失常、心绞痛具有一定的临床价值。
Objective To explore the diagnostic value of 24-hour dynamic electrocardiogram in myocardial ischemia,arrhythmia and angina pectoris of coronary heart disease.Methods A total of 127 outpatients and inpatients who were clinically diagnosed with coronary heart disease were examined by 24-hour dynamic electrocardiogram and routine electrocardiogram.The detection rates of myocardial ischemia,arrhythmia and angina pectoris were compared between two groups.Results The positive rate of myocardial ischemia in dynamic group(90.55%)was significantly higher than that in routine group(34.65%),and the difference was statistically significant(P<0.05).Moreover,the detection rate of arrhythmia in dynamic group was significantly higher than that in routine group(P<0.05).Through dynamic electrocardiogram,variant angina pectoris was detected in 16 cases,but variant angina pectoris was not found by routine electrocardiogram,and the difference in detection rate was statistically significant(P<0.05).Conclusion 24-h dynamic electrocardiogram has certain clinical value in diagnosing myocardial ischemia,arrhythmia and angina pectoris of coronary heart disease.
