Abstract:: 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.
