Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
high-flow rate group
Transesophageal ultrasound
Patients with nonvalvular atrial fibrillation underwent radiofrequency ablation combined with left atrial appendage closure and recovered to sinus rhythm after the operation. To study the changes of left atrial organization and function of two groups of patients with different left atrial appendage emptying speeds.
low-flow rate group
Transesophageal ultrasound
Patients with nonvalvular atrial fibrillation underwent radiofrequency ablation combined with left atrial appendage closure and recovered to sinus rhythm after the operation. To study the changes of left atrial organization and function of two groups of patients with different left atrial appendage emptying speeds.
