Does analysis of amplified sinus-P-wave (APW) allow prediction of left atrial low-voltage substrate (LA-LVS) and estimation of arrhythmia freedom following pulmonary vein isolation (PVI)?
Amplified sinus-P-wave analysis provides a rapid, non-invasive method to predict left atrial low-voltage substrate and estimate arrhythmia freedom after pulmonary vein isolation.
Localization and extent of LA-LVS modifies APW-morphology and -duration. Analysis of APW allows accurate prediction of LA-LVS and enables rapid and non-invasive estimation of arrhythmia freedom following PVI.
Müller‐Edenborn et al. (2019) studied this question.
