Cryoballoon Versus Radiofrequency Ablation for Persistent Atrial Fibrillation: Meta‐Analysis of Randomized Trials

Pacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Introduction Pulmonary vein isolation (PVI) alone achieves modest arrhythmia freedom in persistent atrial fibrillation (PeAF). Cryoballoon ablation (CBA) offers a single‐shot alternative to radiofrequency ablation (RFA) that streamlines procedural workflow.

The Role of Ranolazine in the Treatment of Ventricular Tachycardia and Atrial Fibrillation: A Narrative Review of the Clinical Evidence

Biomedicines
Cardiac arrhythmias are among the leading causes of morbidity and mortality worldwide. While antiarrhythmic drugs traditionally represent the first-line management strategy, their use is often limited by profound proarrhythmic effects.

Rising Comorbidity Burden in Inpatient Atrial Fibrillation Catheter Ablation: Temporal Trends and In‐Hospital Outcomes

Pacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Background Despite advancements in catheter ablation (CA) technique and expertise, success rates of atrial fibrillation (AF) ablation have not substantially improved in recent years. Treating patients with advanced age and higher comorbidities may limit success rates while increasing complications.

Aggravation of induced arrhythmias with antiarrhythmic drugs during electrophysiological testing

, 1985
There is evidence that antiarrhythmic drugs can worsen ventricular arrhythmias in patients. In a previous study ventricular arrhythmias worsened 11% when noninvasive monitoring and exercise tests were performed to evaluate drug effect.

Codocytosis in the Dog: 345 Cases (2020–2022)

Veterinary Clinical Pathology, EarlyView.
ABSTRACT Introduction Codocytes, or target cells, are a morphologic variation of erythrocytes characterized by increased membrane surface area relative to volume. In dogs, codocytosis is frequently noted on blood smear evaluation, but its clinical significance remains poorly understood. Objectives To characterize the clinical conditions associated with

Lifestyle modification in atrial fibrillation: Mechanisms, phenotypes and ablation outcomes

Experimental Physiology, EarlyView.
Abstract Atrial fibrillation (AF) is the most prevalent sustained cardiac arrhythmia and is associated with significant morbidity, mortality and healthcare utilization. Catheter ablation is increasingly used as a rhythm‐control intervention for patients with symptomatic paroxysmal and persistent AF, yet recurrence rates remain suboptimal.

Antiarrhythmic drugs and the importance of beat rate variability in clinical practice

This thesis explores the importance of antiarrhythmic drugs in the treatment of arrhythmia with a focus on evidence-based clinical practice. Although a lot of new drugs have been added to a modernized classification of antiarrhythmic drugs, most of them ...

A new approach to an old disease: Ageing, arrhythmogenic substrate and the role of risk‐factor modification in atrial fibrillation

Experimental Physiology, EarlyView.
Abstract Atrial fibrillation (AF) prevalence rises sharply with age due to two independent mechanisms. Ageing produces irreversible arrhythmogenic substrate changes through progressive fibrosis, cellular senescence and mitochondrial dysfunction, while modifiable risk factors such as obesity, hypertension, sleep apnoea, diabetes and alcohol use promote ...

Electrophysiological Mechanisms of Atrial Flutter

Indian Pacing and Electrophysiology Journal, 2006
Atrial flutter (AFL) is a common arrhythmia in clinical practice. Several experimental models such as tricuspid regurgitation model, tricuspid ring model, sterile pericarditis model and atrial crush injury model have provided important information about
