Does low P-wave amplitude (<0.1 mV) in lead I predict clinical recurrence of paroxysmal atrial fibrillation after radiofrequency catheter ablation?
Low P-wave amplitude (<0.1 mV) in lead I serves as a non-invasive ECG predictor for clinical recurrence of paroxysmal atrial fibrillation following radiofrequency catheter ablation.
Low P-wave amplitude (<0.1 mV) in lead I is related to LA remodelling and displaced inter-atrial conduction pattern to low septum, and independently predicts clinical recurrence after RFCA in patients with PAF.
Park et al. (Mon,) studied this question.
