Abstract
Objective To apply the dynamic electrocardiogram(ECG) to analyze the incidence and clinical significance of various original sites in the patients with myocardial ischemia complicating ventricular premature contraction(VPC).Methods A total of 300 cases of myocardial ischemia complicating VPC in our hospital were selected as the observation group,and contemporaneous 296 healthy people with ventricular premature contractions were selected as the control group.The two groups were performed the examination of 24 h 12-lead dynamic electrocardiogram.The relationship between the VPC occurrence rate at different ventricular original sites and myocardial ischemia was analyzed.Results The occurrence rates of total premature contraction at left ventricular anterior wall,apical site and left ventricle in the observation group were significantly higher than those in the control group;the total premature contraction occurrence rates at right ventricular outflow tract and right ventricle in the control group were significantly higher than those in the observation group,meanwhile premature contraction occurrence rates at left ventricular anterior wall and apical site in the observation group were higher than those at right ventricular anterior wall and apical site,which at right ventricular outflow tract was higher than that at left ventricular outflow tract,the differences were statistically significant(P<0.05).Conclusion Dynamic ECG can effectively detect and evaluate different original sites of premature contraction in the patients with myocardial ischemia complicating VPC,in which the premature contraction at left ventricular anterior wall and apical site is easier to develop complicating myocardial ischemia,meanwhile which provides the important clinical value basis for early diagnosis,treatment and prognosis of myocardial ischemia.关键词
