【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。更多还原

【Abstract】 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.更多还原
