New-onset postoperative atrial fibrillation (POAF) is associated with increased risk of stroke, morbidity, mortality, respiratory failure and pneumonia, with additional treatment and thus increased postoperative cost.1–3 Clinical efforts to prevent and manage life-threatening complications after cardiac surgeries, such as POAF, ...

The Ground-BrEAking Electroporation-based inTervention for Atrial Fibrillation (BEAT-AF) treatment project is an initiative funded by the European Commission from the European Union's Horizon 2020 research and innovation programme, and managed under the European Health and Digital Executive Agency (grant number 945125).1,2 The ...

Highlights The autonomic nervous system plays a critical role in the aetiopathogenesis of atrial fibrillation (AF). Neuromodulation of the autonomic nervous system has been a topic of increased interest in the management of AF. Ablation of ganglionated plexi, ethanol ablation ...

The landscape of managing atrial fibrillation (AF), the most common cardiac arrhythmia and leading cause of stroke, has undergone a period of change following the development of various treatment modalities and risk-modifying strategies designed to mitigate the risk of stroke ...

Catheter ablation has emerged as an effective strategy for the treatment of atrial fibrillation (AF), even becoming a first-line option for selected patients.1 Pulmonary vein isolation (PVI) is the cornerstone of this procedure. Ablation beyond PVI is often practised, but ...

Heart failure (HF) and atrial fibrillation (AF) are inexorably linked. They frequently coexist and share common risk factors, including ageing, hypertension, diabetes, obesity, sleep apnoea and coronary disease.1–4 Over half of patients with HF develop AF at some point,5 and ...

Welcome to the latest edition of European Journal of Arrhythmia & Electrophysiology. Cardiac arrhythmias, the most common of which is atrial fibrillation, represent a substantial health and economic burden worldwide. In the last two decades we have observed major breakthroughs ...

Atrial fibrillation (AF), one of the most common cardiac arrhythmias, is considered to be a significant risk factor for cardiovascular disease, stroke and mortality. The prevalence of AF increases with age, and patients with AF are at risk of atrial ...

Atrial fibrillation (AF) is the most common type of treated cardiac arrhythmia. The prevalence of the condition increases with age, and it presents with a wide spectrum of symptoms and severity. As the population ages, particularly in developed countries, the ...

Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia and a major cause of morbidity and mortality; however, an optimal strategy for its management remains somewhat unclear, especially for patients with persistent AF.1 Electrical cardioversion (ECV) is widely used ...

As clinicians and academics, we have at least three reasons for developing a simple stepwise algorithm for the management of atrial fibrillation (AF) with rapid ventricular response (RVR) in the emergency department (ED). First, AF is the most common rhythm ...
