Objective To investigate the value of dynamic electrocardiogram in diagnosing myocardial ischemia and arrhythmia of patients with coronary heart disease (CHD).
Methods A total of 212 patients with CHD from January 2018 to June 2020 were selected and conducted both dynamic electrocardiogram and routine electrocardiogram.The detection conditions of myocardial ischemia and arrhythmia as well as patient's satisfaction degree were compared between the two methods.
Results The positive rate of myocardial ischemia detected by dynamic electrocardiogram was significantly higher than that by routine electrocardiogram, and the detection rates of symptomatic and asymptomatic myocardial ischemia were significantly higher than that detected by routine electrocardiogram (P < 0.05).Among the detection types of arrhythmias, the detection rates of binary and triple rhythm of atrial escape beats and atrial premature beats, left and right bundle branch block and atrioventricular block by dynamic electrocardiogram were significantly higher than those by routine electrocardiogram (P < 0.05).The patient's total satisfaction degree to dynamic electrocardiogram was 96.22%, which was significantly higher than 75.94% of routine electrocardiogram (P < 0.05).
Conclusion Dynamic electrocardiogram can effectively improve the diagnostic effect of myocardial ischemia and arrhythmia in patients with CHD, and the patient's satisfaction degree is high, which is worthy of clinical application.
