Low P-wave amplitude (< 0.1 mV) in lead I is associated with displaced inter-atrial conduction and clinical recurrence of paroxysmal atrial fibrillation after radiofrequency catheter ablation

摘要

We hypothesized that P-wave amplitude in lead I is related to left atrial (LA) remodelling and inter-atrial conduction pattern, and has a predictive value for recurrence after radiofrequency catheter ablation (RFCA) among patients with paroxysmal atrial fibrillation (PAF).
