Why the study?
With the increasing prevalence of AF in an aging society, early diagnosis and predicting recurrence after ablation remain critical clinical challenges.
Does P wave analysis on electrocardiogram predict new-onset atrial fibrillation and recurrence after ablation?
Does P wave analysis on electrocardiogram predict new-onset atrial fibrillation and recurrence after ablation?
Effect estimate: OR 3.83 (95% CI 1.05-14.05)
p-value: p=0.04
P wave analysis provides a non-invasive and simple method to predict atrial fibrillation onset and post-ablation recurrence, aiding in treatment strategy decisions.
May support post-ablation AF risk stratification; leaves open prospective validation before clinical adoption.
心房細動（af）は超高齢社会において有病率が増加しており，早期診断およびアブレーション後の再発予測が重要な課題である．本稿では，心電図におけるp波に着目し，心房の電気的・構造的リモデリングとの関係，ならびにaf発症および再発との関連について概説する．p波の形態や持続時間，時間的ばらつき，および加算平均心電図による心房遅延電位（a-Lp）の有無は，af新規発症やアブレーション後の再発予測に有用な指標である．特にa-Lp陽性例では再発率が高く，治療戦略において基質修正の重要性を示唆する．また，p波オルタナンスの変化は心房逆リモデリングの指標ともなりうる．p波解析は，非侵襲的かつ簡便に得られる情報として，afの病態理解と治療方針決定に寄与する可能性がある．

Fukaya et al. (2025) conducted a review in Atrial fibrillation. P wave analysis (including P-SAECG and P wave alternans) was evaluated on Atrial fibrillation recurrence after catheter ablation (predicted by A-LP positivity) (OR 3.83, 95% CI 1.05-14.05, p=0.04).
