RESUMO
PURPOSE: This study aims to compare the clinical effects of dynamic electrocardiograms (ECGs) and conventional ECGs in the diagnosis of arrhythmic coronary atherosclerotic heart disease. METHODS: Fifty patients with arrhythmic coronary atherosclerotic heart disease admitted to our hospital from January 2019 to January 2020 were recruited as the study cohort. All the 50 patients were first diagnosed using conventional ECGs, and then they were diagnosed using 24-hour dynamic ECGs. The results of the conventional ECG diagnoses were taken as the control group, and the results of 24-hour dynamic ECG diagnoses were taken as the experimental group. The positive detection rates, the ventricular premature contraction rates, the supraventricular tachycardia rates, the atrioventricular block detection rates, the paired atrial premature beats, and the paired ventricular premature beats were compared between the two groups, and the diagnostic effectiveness of the dynamic electrocardiograms and the conventional electrocardiograms was analyzed. RESULTS: The positive detection rate in the experimental group was significantly higher than it was in the control group (P<0.05). The atrioventricular block, paired atrial premature beat, and paired ventricular premature beats rates in the experimental group were found to be significantly higher (P<0.05). There were no significant differences in the atrial fibrillation and premature ventricular beat rates between the two groups (P>0.05). CONCLUSION: Dynamic electrocardiograms are better for diagnosing arrhythmic coronary atherosclerotic heart disease than conventional electrocardiograms.
