Chronic beta-adrenoceptor blockade and human atrial cell electrophysiology: evidence of pharmacological remodelling [PDF]

, 2003
<b>Objective:</b> Chronic beta-adrenoceptor antagonist (β-blocker) treatment reduces the incidence of reversion to AF in patients, possibly via an adaptive myocardial response.

Explainable Machine Learning to Predict Anchored Reentry Substrate Created by Persistent Atrial Fibrillation Ablation in Computational Models

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2023
Background Postablation arrhythmia recurrence occurs in ~40% of patients with persistent atrial fibrillation. Fibrotic remodeling exacerbates arrhythmic activity in persistent atrial fibrillation and can play a key role in reentrant arrhythmia, but ...

Cardiac adrenergic control and atrial fibrillation [PDF]

, 2010
Atrial fibrillation (AF) is the most common cardiac arrhythmia, and it causes substantial mortality. The autonomic nervous system, and particularly the adrenergic/cholinergic balance, has a profound influence on the occurrence of AF ...

Investigation of the predictors of transition to persistent atrial fibrillation in patients with paroxysmal atrial fibrillation [PDF]

Clinical Cardiology, 2002
AbstractBackground: Until now, no clinically useful indicators have existed that predict the transition from paroxysmal to persistent atrial fibrillation (AF).Hypothesis: The current prospective study was conducted for identifying predictors of progression to persistent AF over the long term.Methods: We studied 102 consecutive patients (mean age: 55 ...
