Abstract:
Objective To observe the changes of left atrial dimension and f unction before and after cardioversion for atrial fibrillation (AF) and the rela tion between dimension and function.Methods Among 94 cases,34 ca ses who had spontaneous cardioversion converted to sinus rhythm,60 cases were ra ndomly grouped into 31 cases with drug cardioversion and 29 cases with direct-c urrent shock.Left atrial diameter,volume and A-wave velocity were measured to e valuate left atrial dimension and function using Dopplor echocardiogram in all c ases before and after cardioversion.Results After conversion,Lef t atrial diameter and volume decreased remarkably (P
