Abstract
Objective
To investigate the correlation between ventricular arrhythmias and left ventricular systolic function in patients with acute myocardial infarction (ecg).
Methods
Select 150 cases of patients with acute myocardial infarction (mi) into the study, and based on the grouping of 12-lead electrocardiogram QRS wave form, divided into group B (n=50, pathologic Q wave), group A (n=50, fragmented QRS wave), group C (n=50, cataclastic QRS wave merging pathologic Q wave). The correlation between ventricular arrhythmia and left ventricular systolic function was analyzed.
Results
Group B Ⅳ grade A and B Ⅳ, Ⅴ incidence of ventricular arrhythmia was lower than that in group A and group C(P<0.05); The LVDD in group B was lower than group A and group C (P<0.05), while LVEF was higher than group A and group C (P<0.05).
Conclusion
The electrocardiogram of patients with acute myocardial infarction was associated with ventricular arrhythmias, and the left ventricular systolic function decreased significantly.
