Clinical value of fibrillatory wave amplitude on surface ECG in patients with persistent atrial fibrillation

We postulated that amplitude of fibrillatory (F)-wave in patients with persistent AF would correlate with clinical characteristics and outcome in patients undergoing catheter ablation for AF. Maximal and mean amplitude of F-waves were measured in V1 and lead II in 90 patients prior to ablation for persistent AF. F-wave amplitudes were correlated to clinical, echocardiographic variables, and outcome. F-wave ≥ 0.1 mV in lead II and V1was...
