The purpose of the study is to assess the reconstruction and inverse reconstruction in right atrium by speckle tracking echocardiography combined with real-time three dimensional echocardiography for atrial fibrillation patients before and after radiofrequency ablation (RFCA)
The prevalence of atrial fibrillation (AF) has increased in recent years. The construction and function of right atrium haven't shown clearly before and after radiofrequency ablation (RFCA).The purpose of the study is to investigate whether RFCA can lead to inverse reconstruction of right atrium for atrial fibrillation patients, which diagnosing by speckle tracking echocardiography combined with real-time three dimensional echocardiography. All patients will be followed up for 12 months.
