Why the study?
Does prolonged P-wave duration (≥150 ms) on amplified 12-lead ECG predict left atrial low voltage substrate and arrhythmia recurrence in patients with persistent atrial fibrillation undergoing pulmonary vein isolation?
Does prolonged P-wave duration (≥150 ms) on amplified 12-lead ECG predict left atrial low voltage substrate and arrhythmia recurrence in patients with persistent atrial fibrillation undergoing pulmonary vein isolation?
Prolonged P-wave duration (≥150 ms) on amplified 12-lead ECG serves as a non-invasive predictor of left atrial low voltage substrate and arrhythmia recurrence after PVI in patients with persistent AF.
May support pre-ablation PWD for recurrence risk stratification in persistent AF; leaves open need for prospective validation.
Advanced arrhythmogenic LVS is associated with significant intra-atrial conduction delay, which is accurately measurable by prolongation of PWD on amplified 12-lead ECG. PWD ≥150 ms during sinus rhythm measured prior to ablation identifies patients with persistent AF who are at increased risk for arrhythmia recurrence following PVI.
