Analysis of the Clinical Application Effect and Accuracy of Dynamic Electrocardiogram in the Diagnosis of Arrhythmia in patients with Coronary Heart Disease
Objective To explore the clinical application effect and accuracy of dynamic electrocardiogram in the diagnosis of arrhythmia in patients with coronary heart disease.Methods A total of 100 patients with sus-pected coronary heart disease and arrhythmia admitted to Yishui County Mazhan People's Hospital from Febru-ary 2022 to January 2023 were randomly selected as the research objects.Conventional electrocardiogram,dy-namic electrocardiogram and coronary angiography were tested respectively,and the detection results of coro-nary angiography were used as the gold standard to analyze the diagnostic efficiency of conventional electrocar-diogram and dynamic electrocardiogram.Results 100 suspected patients underwent coronary angiography,and 91 cases were confirmed,including 42 cases of atrial arrhythmia,31 cases of ventricular arrhythmia,10 cases of conduction block,6 cases of sinus and sinus bradycardia,and 2 cases of junctional arrhythmias.The detection rate of dynamic electrocardiogram was 98.90%(90/91),higher than the detection rate of conventional electrocar-diogram(68.13%)(62/91),and the difference was statistically significant(P<0.05).The accuracy and sensitivity of dynamic electrocardiogram in diagnosing coronary heart disease were 95.00%and 96.70%respectively,which were higher than 65.00%and 64.84%of conventional electrocardiogram respectively,and the difference was statistically significant(χ2=28.125,29.750,both P<0.05).The diagnostic accordance rate of dynamic elec-trocardiogram for ventricular arrhythmia,atrial arrhythmia,junctional arrhythmia,sinus arrest,and sinus brady-cardia were higher than those of conventional electrocardiogram,and the differences were statistically signifi-cant(all P<0.05).However,there was no statistical significant difference in the diagnostic accordance rates of conduction block between the two examination methods(P>0.05).Conclusion The clinical application of dy-namic electrocardiogram in the diagnosis of arrhythmia in patients with coronary heart disease has significant ef-fect.
