Antiarrhythmics for maintaining sinus rhythm after cardioversion of atrial fibrillation.

Atrial fibrillation is the most frequent sustained arrhythmia. Atrial fibrillation often recurs after restoration of normal sinus rhythm. Antiarrhythmic drugs have been widely used to prevent recurrence. This is an update of a review previously published in 2006, 2012 and 2015.

Early or delayed cardioversion in atrial fibrillation?

Atrial fibrillation is one of the most common arrhythmias. As the symptoms can be abrupt in onset it is associated with a substantial burden on the medical emergency system. By routine practice patients with symptomatic atrial fibrillation of a duration less than 48 hours are commonly offered cardioversion therapy. Data from a recent study shows that more than two thirds of patients convert to sinus rhythm spontaneously within 48 hours. A watch-and-wait approach in rhythm control management may be suggested...

Left atrial mechanical remodelling assessed as the velocity of left atrium appendage wall motion during atrial fibrillation is associated with maintenance of sinus rhythm after electrical cardioversion in patients with persistent atrial fibrillation.

The velocity of left atrium appendage (LAA) wall motion during atrial fibrillation (AF) is a potential marker of mechanical remodelling. In this study, we investigated whether the velocity of LAA wall motion during AF predicted the success of electrical cardioversion and long-term sinus rhythm maintenance. Standard echocardiographic data were obtained by transthoracic echocardiography, and LAA wall motion velocities were measured by transoesophageal echocardiography. With logistic regression and receiver op...

Cardioversion efficacy of nifekalan in patients with sustained atrial fibrillation after radiofrequency ablation.

To evaluate the efficacy and safety of nifekalan (NIF) on cardioversion in atrial fibrillation (AF) patients post radiofrequency ablation, and investigate the relevant factors related to the cardioversion efficacy of NIF. We screened patients with sustained AF rhythm after radiofrequency ablation between November 2016 and July 2018. Participants were treated with intravenous NIF 0.4 mg/kg within 5-10 minutes after ablation. We observed the adverse reaction, and monitored the rhythm, heart rate, QT interval...

Is delayed cardioversion the better approach in recent-onset atrial fibrillation? Yes.

Atrial fibrillation is the most common sustained arrhythmia encountered in primary care practice and represents a significant burden on the health care system with a higher than expected hospitalization rate from the emergency department. The first goal of therapy is to assess the patient's symptoms and hemodynamic status. There are multiple acute management strategies for atrial fibrillation including heart rate control, immediate direct-current cardioversion, or pharmacologic cardioversion. Given the vari...

Hot off the Press: Chemical vs. Electrical Cardioversion for Atrial Fibrillation.

Atrial Fibrillation (AF) is a significant dysrhythmia that often requires treatment in the emergency department (ED). This can be performed with rhythm control using electrical or chemical cardioversion, or with rate control. There is widespread variation in management of AF within Canada and worldwide. This study focuses on rhythm control techniques, comparing emergency department length of stay when using an electrical-first strategy versus a chemical-first strategy of cardioversion.

Improved brain perfusion after electrical cardioversion of atrial fibrillation.

Atrial fibrillation (AF) has been associated with reduced brain volume, cognitive impairment, and reduced cerebral blood flow. The causes of reduced cerebral blood flow in AF are unknown, but no reduction was seen in individuals without the arrhythmia in a previous study. The aim of this study was to test the hypothesis that brain perfusion, measured with magnetic resonance imaging (MRI), improves after cardioversion of AF to sinus rhythm (SR).

Thromboembolic events around the time of cardioversion for atrial fibrillation in patients receiving antiplatelet treatment in the ACTIVE trials.

It is unknown whether cardioversion of atrial fibrillation causes thromboembolic events or is a risk marker. To assess causality, we examined the temporal pattern of thromboembolism in patients having cardioversion.

Outcomes following cardioversion for patients with cardiac amyloidosis and atrial fibrillation or atrial flutter.

Atrial arrhythmias commonly occur in patients with cardiac amyloidosis (CA), but there is limited data on safety or efficacy of cardioversion (DCCV) for management of these rhythms in CA. We identified 25 patients with CA (20 with transthyretin (TTR) and 5 with light-chain (AL) amyloidosis) at Duke University who underwent DCCV for atrial arrhythmias and documented procedural success, complications, and long-term morbidity and mortality. While DCCV successfully restored sinus rhythm in 96% of patients, 36% ...

Mechanical atrial recovery after cardioversion in persistent atrial fibrillation evaluated by bidimensional speckle tracking echocardiography.

Atrial fibrillation induces reversible electrical and mechanical modifications (atrial remodeling). Atrial stunning is a mechanical dysfunction with preserved bioelectrical function, occurring after successful atrial fibrillation electrical cardioversion (ECV). Two-dimensional speckle tracking echocardiography is a new technology for evaluating atrial mechanical function. We assessed atrial mechanical function after ECV with serial two-dimensional speckle tracking echocardiography evaluations. The investiga...

Atrial Fibrillation Induced From Commotio Cordis.

A 20-year-old male collegiate basketball player was evaluated for sudden chest pain, shortness of breath, dizziness, and blurry vision, following an elbow to the anterior chest by another player. His symptoms improved over 10 minutes of observation, but rhythm strip performed onsite showed atrial fibrillation, and the athlete was transmitted to the emergency department for further evaluation. Electrocardiogram in the ER confirmed atrial fibrillation with a rate of 85 bpm. Electrocardioversion was being arra...

Cardiac MRI and Fibrosis Quantification.

Left atrial fibrosis plays an important role in the pathophysiology of atrial fibrillation. Left atrial ablation is an effective and increasingly used strategy to restore and maintain sinus rhythm in patients with atrial fibrillation. Late gadolinium enhancement (LGE) MRI and custom image analysis software have been used to visualize and quantify preablation atrial fibrosis and postablation scar and new fibrosis formation. This article reviews technical aspects of imaging atrial fibrosis/scar by LGE-MRI; us...

Severe and uniform bi-atrial remodeling measured by dominant frequency analysis in persistent atrial fibrillation unresponsive to ablation.

High values of ECG and intracardiac dominant frequency (DF) are indicative of significant atrial remodeling in persistent atrial fibrillation (peAF). We hypothesized that patients with peAF unresponsive to ablation display higher ECG and intracardiac DFs than those remaining in sinus rhythm (SR) on the long term.

Cabins, castles, and constant hearts: rhythm control therapy in patients with atrial fibrillation.

Recent innovations have the potential to improve rhythm control therapy in patients with atrial fibrillation (AF). Controlled trials provide new evidence on the effectiveness and safety of rhythm control therapy, particularly in patients with AF and heart failure. This review summarizes evidence supporting the use of rhythm control therapy in patients with AF for different outcomes, discusses implications for indications, and highlights remaining clinical gaps in evidence. Rhythm control therapy improves sy...

Atrial fibrillation and stroke: how much atrial fibrillation is enough to cause a stroke?

The association between atrial fibrillation and stroke is firmly established, and anticoagulation reduces stroke risk in patients with atrial fibrillation. However, the role of anticoagulation in very brief durations of atrial fibrillation (subclinical atrial fibrillation) is an area of controversy.

A High BNP Level Predicts an Improvement in Exercise Tolerance after a Successful Catheter Ablation of Persistent Atrial Fibrillation.

Restoration of sinus rhythm (SR) by catheter ablation (CA) of atrial fibrillation (AF) improves exercise tolerance. However, it is still unclear what characteristics of patients are contributing to an improvement in exercise tolerance after CA of AF without heart failure.

Isolated Left Atrial Standstill in Patients with Hypertrophic Cardiomyopathy and Atrial Fibrillation after Restoration of Sinus Rhythm.

Effect of acute and chronic ethanol on atrial fibrillation vulnerability in rats.

Even though ethanol consumption has been associated with risk of atrial fibrillation (AF), little is known about how ethanol affects atrial electrophysiology.

Correlation between atrial premature depolarisations after electrical cardioversion and risk for atrial fibrillation recurrence in horses.

Determinants of sinus rhythm maintenance in patients with early-persistent atrial fibrillation and heart failure.

Potassium infusion increases the likelihood of conversion of recent-onset atrial fibrillation-A single-blinded, randomized clinical trial.

The optimal antiarrhythmic management of recent-onset atrial fibrillation (ROAF) or atrial flutter is controversial and there is a considerable variability in clinical treatment strategies. It is not known if potassium infusion has the potential to convert ROAF or atrial flutter to sinus rhythm (SR). Therefore, we aimed to investigate if patients with ROAF or atrial flutter and plasma-potassium levels ≤4.0 mmol/L have increased probability to convert to SR if the plasma-potassium level is increased toward...

Effect of the variability of blood pressure, glucose, total cholesterol, and body mass index on risk of atrial fibrillation in a healthy population.

The variability of metabolic parameters might have an impact on the pathophysiology of atrial fibrillation (AF).

Improving Exercise Tolerance with Catheter Ablation.

The growing epidemic of atrial fibrillation (AF) has placed an increasing demand on the need for catheter ablation as a strategy to provide rhythm control amongst symptomatic AF patients, refractory to anti-arrhythmic medication. Despite the well documented benefits of AF rhythm control, the maintenance of sinus rhythm following catheter ablation of persistent AF, occurs in approximately 43% of patients after a single procedure and 69% of patients following multiple procedures .
