Why the study?
Is P-wave duration and dispersion increased in patients with aortic stenosis compared to those without?
Is P-wave duration and dispersion increased in patients with aortic stenosis compared to those without?
Patients with aortic stenosis exhibit increased P-wave duration and dispersion, which may serve as markers for an increased risk of paroxysmal atrial fibrillation.
May signal elevated paroxysmal AF risk in aortic stenosis; leaves open prospective validation before clinical use.
PWD, indicating increased risk for paroxysmal AF, was found to be significantly higher in patients with AS than in those without it. Further assessment of the clinical utility of PWD for the prediction of paroxysmal AF in patients with severe AS will require longer prospective studies.
