ABSTRACT
Objective:
To explore diagnostic value of exercise ECG and dynamic ECG (DCG)for organic heart disease (OHD)ventricular premature beat (VPB).Methods:
A total of 135 VPB patients were selected from our hospital.Ac-cording to examination outcome,they were divided into OHD group (n=75)and non-OHD group (n=60).Results of ex-ercise ECG and DCG were compared between two groups.Results:
Compared with non-OHD group,there were significant reductions in percentages of Lown grade Ⅰ and Ⅱ,and significant rise in percentages of Lown grade Ⅲ,IV-A and IV-B in OHD group,P <0.05 or <0.01. DCG indicated that compared with non-OHD group,there was significant reduction in percentage of type B (90.0% vs.14.67%),and significant rise in percentages of type A (1.67% vs.49.33%)and D (0% vs.34.67%)in OHD group,P =0.001 all;exercise ECG indicated that compared with non-OHD group,there was significant reduction in percentage of type E (61.67% vs.14.67%),and significant rise in percentages of type F (38.33%vs.85.33%)and ischemic ST segment change (0% vs.40.0%)in OHD group,P =0.001 all.Compared with non-OHD group,there were significant rise in incidence rates of atrial premature beat,paroxysmal supraventricular tachycardia,atrial flutter in OHD group,P <0.05 or <0.01.Sensitivity,specificity,positive and negative predictive value and accuracy of exercise ECG and DCG were higher both,and there were no significant difference between two groups (P >0.05 all).Conclusion:
Diagnostic value of exercise ECG and DCG are significant for organic heart disease ventricular premature beat, but it is no significant difference between two methods,which is worth extending.
