Duration of heart failure and the risk of atrial fibrillation: different mechanisms at different times? [PDF]

, 2009
Chronic heart failure increases the risk of atrial fibrillation (AF), with the prevalence of AF paralleling the severity of heart failure.1 Factors that underlie this increased susceptibility to AF may include electrical, structural, and neurohumoral ...

Focal impulse and rotor modulation of atrial rotors during atrial fibrillation leads to organization of left atrial activation as reflected by waveform morphology recurrence quantification analysis and organizational index

Journal of Arrhythmia, 2020
Background Focal impulse and rotor modulation (FIRM) can cause slowing, organization, and occasionally termination of atrial fibrillation (AF), although results have been mixed.

Mechanisms of termination and prevention of atrial fibrillation by drug therapy [PDF]

, 2011
Atrial fibrillation (AF) is a disorder of the rhythm of electrical activation of the cardiac atria. It is the most common cardiac arrhythmia, has multiple aetiologies, and increases the risk of death from stroke.

Novel concepts in atrial fibrillation ablation—breaking the trade‐off between efficacy and safety

Journal of Arrhythmia, 2021
Despite substantial technological and procedural advances that have improved the efficacy and safety of AF ablation in recent years, the long‐term durability of ablation lesions is still not satisfactory.

Electrophysiological and arrhythmogenic effects of 5-hydroxytryptamine on human atrial cells are reduced in atrial fibrillation [PDF]

, 2007
5-Hydroxytryptamine (5-HT) is proarrhythmic in atrial cells from patients in sinus rhythm (SR) via activation of 5-HT₄ receptors, but its effects in atrial cells from patients with atrial fibrillation (AF) are unknown.
