Abstract：Objective To investigate the application value of echocardiogram in evaluating the left atrial function in patients with coronary artery disease and atrial fibrillation .Methods Twenty-five cases of patients with coronary heart disease and atrial fibrillation and 22 cases of patients with atrial fibrillation and sinus arrhythmia were taken respectively as the atrial fibrillation group (n=25) and sinus rhythm group(n=22).Other 20 persons admitted to the hospital for medical examination during the same period were taken as the control group (n=20).They were all examined by color Doppler ultrasonography .The size and volume of left atrial were respectively measured by conven-tional echocardiography and Doppler technique was used to measure the blood flow spectrum of the mitral valve and pulmonary venous flow spectrum .Results The data of LAD , LAVmax and LAVmin in the atrial fibrillation group were respectively (43.26 ±2.81)mm, (41.61 ±2.63)ml and (20.12 ±1.53)ml, which were significantly higher than those in the sinus rhythm group and the control group , but the data in the control group were the lowest ( P<0.05 ) .There were significant differences in the data of E , E-VTI, A, A-VTI and E/A between the atrial fibrillation group, sinus rhythm group and the control group (P<0.05).Among them, the data of E, E-VTI in the atrial fibril-lation group increased , while the data of E , E-VTI in the sinus rhythm group decreased , and the data of A and A-VTI in the atrial fibrillation group decreased while the data of E and E-VTI in the sinus rhythm group increased , with sig-nificant difference ( P<0.05 ) .Compared with the control group , the data of A in the sinus rhythm group decreased ( P<0.05 ) .But the indexes of other pulmonary venous blood spectrum had no significant differences ( P>0.05 ) . Compared with the control group , the data of S , S-VTI in the atrial fibrillation group decreased but the data of D peak and D-VTI increased, S/D<1,(P<0.05).Conclusion Echocardiogram can accurately reflect left atrial function in patients with atrial fibrillation and atrial fibrillation .
