dimensional echocardiogram

Methods: The various left ventricular function indexes of elderly idiopathic patients with persistent AF ( group ⅰ), paroxysmal AF ( group ⅱ), and after cardioversion ( group ⅲ) were determined by two dimensional and doppler color echocardiogram, compared with normal elders ( control group).
