Abstract Objective: To explore the left ventricular systolic function in patients with atrial fibrillation(AF) and normal left ventricular ejection fraction(LVEF) using automated function imaging(AFI). Methods: Thirty patients with AF and normal LVEF were enrolled as AF group and thirty matched subjects as control group, left atrial diameter(LAd), left ventricular end-diastolic diameter(LVEDd), left ventricular end-systolic diameter(LVESd), LVEF were measured. The left ventricular strain of(GLPS-LAX, GLPS-A4C, GLPS-A2C) and average strain(GLPS-AVG) were acquired by AFI function. Results: General ultrasound: age, heart rate, LAD, LVEDd, LVESd were higher in the AF group than those in the control group(P<0.05), while there was no significant difference of LVEF between the two groups. GLEF-LAX, GLPS-A4C, GLPS-A2C and GLPS-AVG in the AF group were significantly lower than those in the control group(P<0.05). Conclusion: Although the LVEF is normal in patients with AF, the left ventricular myocardial segment systolic function and overall systolic function have been reduced. AFI function can evaluate left ventricular systolic function in patients with AF quickly and quantitatively and provide valuable clinical information.
