2023年9月22日 · The restoration (cardioversion) to sinus rhythm (SR) from atrial fibrillation (AF) is performed primarily to improve symptoms, but it may also prevent tachycardia-induced cardiomyopathy, facilitate management of heart failure, and reduce the risk of inappropriate shocks in those with implanted defibrillators.

Generally cardioversion while anti-coagulated is believed to be safe with a 1.3% risk of thromboembolism if on aspirin or other anticoagulant However the risk may be as great as 2% risk after 48 hours and preference should be given to anticoagulation prior to …

2001年10月23日 · Perform immediate electrical cardioversion in patients with acute paroxysmal AF and a rapid ventricular response associated with acute myocardial infarction, symptomatic hypotension, angina, or cardiac failure that does not respond promptly to …

Cardioversion, either by a synchronized direct current (DC) electrical shock (electrical cardioversion, ECV) or by the application of antiarrhythmic drugs (AADs; pharmacological cardioversion, PCV), is an integral part of the management of atrial fibrillation (AF) and atrial flutter (AFL) in symptomatic patients who require a rhythm control ...

Cardioversion is appropriate for low-risk patients presenting within 48 hours of known onset. All other patients, including those with unknown time of AF onset, prior stroke/transient ischemic attack, mitral valve disease, or mechanical heart valve, should undergo

2021年3月14日 · Patients with atrial fibrillation who are unstable due to an RVR should be treated with synchronized cardioversion. Diltiazem, at a dose of 0.25 mg/kg, is the first-line medication for most patients with atrial fibrillation with an RVR.

Starting healthier habits, taking medications and having procedures can help you manage A-fib with RVR. Without treatment, A-fib with RVR can lead to heart disease, heart failure or a stroke. Catheter ablation provides an effective, minimally invasive treatment of atrial fibrillation.

2023年12月1日 · When AF occurs in the context of a rapid ventricular rate/response (RVR), this can lead to complications, including hypoperfusion and cardiac ischemia. Emergency physicians play a key role in the diagnosis and management of this dysrhythmia. This paper evaluates key evidence-based updates concerning AF with RVR for the emergency clinician.

2020年12月16日 · Atrial fibrillation with RVR is the natural course of atrial fibrillation with a high conduction rate to the ventricles leading to rapid ventricular contraction. It is defined as atrial fibrillation with a ventricular rate over 100bpm.

Elective cardioversion is a safe option for select patients and may reduce AF symptoms and risk of AF recurrence. Rate control using beta blockers or calcium channel blockers should be pursued in those with AF with RVR who do not undergo cardioversion.
