Change in P wave morphology after convergent atrial fibrillation ablation
Indian Pacing and Electrophysiology Journal, 2016 Convergent atrial fibrillation ablation involves extensive epicardial as well as endocardial ablation of the left atrium. We examined whether it changes the morphology of the surface P wave.

Atrial conduction explains the occurrence of the P‐wave dispersion phenomenon, but weakly
Journal of Arrhythmia, 2020 Background P‐wave dispersion (PWD) is believed to be caused by inhomogeneous atrial conduction. This statement, however, is based on limited little solid evidence.

Effect of transcatheter aortic valve replacement on P-wave duration, P-wave dispersion and left atrial size. [PDF]
J Geriatr Cardiol, 2015 Background P-wave dispersion (PWD), a measure of heterogeneity of atrial refractoriness, is defined as the difference between the maximum and minimum P-wave duration.

P-Wave and QRS complex duration.
, 2015 Uncomplicated pregnancy, was not associated with alterations in P-Wave or QRS duration compared to never-pregnant controls. Late postpartum (6–8 months), PE subjects exhibited increased duration in both P-wave and QRS complexes.
