Diagnostic value of dynamic electrocardiogram in myocardial ischemia and arrhythmia in elderly patients with coronary heart disease
Objective To investigate the diagnostic value of dynamic electrocardiogram in myocardial ischemia and arrhythmia in elderly patients with coronary heart disease.Methods 100 elderly patients with coronary heart disease were taken as the research subjects.All patients underwent dynamic electrocardiogram and routine electrocardiogram.The detection rate of electrocardiogram abnormality,detection of myocardial ischemia,arrhythmia,myocardial ischemia site and changes of ST segment were compared between the two methods,and the diagnostic efficiency for myocardial ischemia.Results The detection rates of dynamic electrocardiogram for paired premature ventricular contractions,short runs of paroxysmal supraventricular tachycardia,bigeminy or trigeminy of atrial premature beats,atrial premature beats,bigeminy or trigeminy of ventricular premature beats,ventricular premature beats were 39%,40%,36%,42%,51%and 58%,which were significantly higher than 24%,16%,15%,20%,35%,28%of routine electrocardiogram(P<0.05).The detection rates of dynamic electrocardiogram were 75%for myocardial ischemia,71%for arrhythmia,16%for inferior myocardial ischemia,12%for lateral myocardial ischemia,46%for ST segment elevation,and 48%for ST segment depression,and the detection rates of routine electrocardiogram were 52%,50%,4%,2%,23%and 18%.The detection rates of dynamic electrocardiogram for myocardial ischemia,arrhythmia,inferior myocardial ischemia,lateral myocardial ischemia,ST segment elevation,and ST segment depression were significantly higher than those of routine electrocardiogram(P<0.05).The sensitivity and accuracy of dynamic electrocardiogram examination for myocardial ischemia were 97%(68/70)and 91%(91/100),respectively,which were significantly higher than 50%(35/70)and 48%(48/100)of routine electrocardiogram examination(P<0.05).Conclusion The application of dynamic electrocardiogram in elderly patients with coronary heart disease has an active therapeutic effect on the diagnosis of myocardial ischemia and arrhythmia.It can provide accurate and reliable basis for patients to carry out treatment,effectively enhance the therapeutic effect of patients,and is worth promoting in clinical practice.
