Abstract：Objective To evaluate the changes of right ventricular morphology and function in patients with atrial fibrillation by using real-time three-dimensional echocardiography and speckle tracking imaging. Methods A total of 45 patients with paroxysmal atrial fibrillation clinically diagnosed in the First Affiliated Hospital of Xinjiang Medical University (hereinafter referred to as “our hospital”) from September 2017 to April 2020 were selected as the atrial fibrillation group, at the same time, 45 healthy patients with normal heart were selected as the control group. The relevant parameters of right ventricular structure and function were obtained by two-dimensional ultrasound, real-time three-dimensional echocardiography, and speckle tracking imaging. Results Left atrium anterior-posterior diameter, left ventricular end diastolic volume, left ventricular end systolic volume, right ventricular end diastolic volume, and right ventricular end systolic volume in the atrial fibrillation group were higher than those in control group, and left ventricular ejection fraction, right ventricular ejection fraction, right ventricular fractional area change, and tricuspid annular plane systolic excursion were lower than those in the control group (P < 0.05); there were no significant differences in left ventricular stroke volume, right atrial left-right diameter, right ventricular dimension, and right ventricular stroke volume between the two groups (P > 0.05). Right ventricular longitudinal strain of free-wall, right ventricular longitudinal strain of septum, basal segment of right ventricular free-wall systolic peak strain, middle segment of right ventricular free-wall systolic peak strain, basal segment of right ventricular septum systolic peak strain, middle segment of right ventricular septum systolic peak strain, and right ventricular global longitudinal strain in the atrial fibrillation group were lower than those in the control group (P < 0.05); there were no significant differences in apical segment of right ventricular free-wall systolic peak strain and apical segment of right ventricular septum systolic peak strain between the two groups (P > 0.05). Conclusion The myocardial contraction of right ventricle in patients with atrial fibrillation is weaker, and the reduction of right ventricular inflow tract is more obvious. Real-time three-dimensional echocardiography and speckle tracking imaging assessment can provide diagnostic information for evaluating changes in right ventricular function in patients with atrial fibrillation.
