causing a repeated loop of electrical activity to depolarize the atrium at a rate of about 250 to 350 beats per minute; the atrial rate in atrial fibrillation is 400 to 600 bpm. Just as in atrial ...

Atrial fibrillation occurs when action potentials fire very rapidly within the pulmonary veins or atrium in a chaotic manner. The result is a very fast atrial rate — about 400 to 600 beats per ...

"Atrial fibrillation is an incredibly common disease, yet we have very limited pharmacologic therapies because we still have a primitive understanding of the molecular mechanisms involved," said ...

Pulmonary-vein isolation is an effective treatment for paroxysmal atrial fibrillation. Pulsed field ablation (PFA) is a nonthermal ablation method with few adverse effects beyond the myocardium.

Background: Several clinical factors have been studied to predict atrial fibrillation (AF) recurrence after electrical cardioversion (ECV) with limited predictive value. Methods: A method able to ...
