Abstract:
Objective To explore the mechanism and clinical significance of left atrioventricular interval abnormality in the patients with coronary artery disease.Methods A total of 48 patients with coronary artery disease were selected and divided into the left interval atrioventricular shortening group(AV≤100 ms) and the left atrioventricular interval normal group(AR＞100 ms) according to the left atrioventricular interval measured by the esophageal electrocardiogram.The clinical features,cardiac echocardiography and coronary vessel lesions were compared between the two groups.Results The age in the AR≤ 100 ms group was higher than that in the AR＞10 ms group(P=0.018);the proportion of right coronary arterial lesion in the AR ≤ 100 ms group was higher in that in the AR＞10ms group(P=0.038);the left atrial diameter in the AR ≤100ms group was enlarged compared with that in the AR＞ 100 ms group(P=0.041).Conclusion The cardiac electric transduction abnormality exists in the patients with coronary heart disease,the majority of the patients with left atrioventricular interval shortening have the right coronary artery lesion.
