RÉSUMÉ
Objective To investigate and compare the clinical values of routine electrocardiogram and dynamic electrocardiogram in arrhythmia in coronary heart disease diagnosis.Methods 73 patients with coronary heart disease were collected and monitored by routine electrocardiogram and dynamic electrocardiogram,and two groups were e stablished including control group using routine electrocardiogram and observation group using dynamic electrocardiogram.The positive diagnosis rate and the specific diagnosis diresults of arrhythmia in coronary heart disease of both groups were compared.Results The positive diagnosis rate of arrhythmia in coronary heart disease of observation group(75.3％ ) was significantly higher than that of control group(54.8％ ) ( x2 =6.78,P ＜0.05).And the positive diagnosis rate of the observation group was also significantly higher than that of the control group in ventricular premature beats two,triple law,pairs of premature ventricular contractions,atrial premature beats two,triple law,atrial premature beats in pairs,atrioventricular block and paroxysmal ventricular tachycardia( all P ＜ 0.05 ).Conclusion Compared with routine electrocardiogram,the dynamic electrocardiogram in anrnythmia in coronary heart disease diagnosis could obtain higher positive diagnosis rate,and it is worthy of clinical application.
