A study explored P-wave alternans (PWA) as a biomarker for assessing and predicting atrial fibrillation recurrence after pulmonary vein isolation (PVI) therapy.
Patients who underwent PVI showed a significant decrease in PWA following the procedure, with further monitoring indicating that those with a rebound in PWA levels at follow-up were more likely to experience recurrent atrial arrhythmias.
The findings suggest that tracking PWA using AI algorithms post-PVI can effectively predict atrial arrhythmia recurrence, highlighting its potential in clinical settings.
