Do prolonged P-wave duration and interatrial block predict new-onset atrial fibrillation?
P-wave duration and interatrial block are independent predictors of new-onset atrial fibrillation and could serve as criteria for intensive AF screening.
Interatrial block is an independent predictor of new-onset AF. The association is stronger for patients with implantable devices (close monitoring). Thus, PWD and IAB could be used as selection criteria for intensive screening, follow-up or interventions.
