Cardioversion is a medical procedure by which an abnormally fast heart rate (tachycardia) or other cardiac arrhythmia is converted to a normal rhythm using electricity or drugs. Synchronized electrical cardioversion uses a therapeutic dose of electric current to the heart at a specific moment in the cardiac cycle , restoring the activity of the ...
In the absence of shock, inhibition at the AV node is attempted. This is achieved first by a trial of specific physical maneuvers such as holding a breath in or bearing down. If these maneuvers fail, using intravenous adenosine [ 4 ] causes complete electrical blockade at the AV node and interrupts the reentrant electrical circuit.
Cardioversion is either achieved pharmacologically or via the application of a shock synchronized to the underlying heartbeat. It is used for the treatment of supraventricular tachycardias. In elective cardioversion, the recipient is usually sedated or lightly anesthetized for the procedure. Defibrillation differs in that the shock is not ...

Treatment may be with specific physical maneuvers, medications, or, rarely, synchronized cardioversion. Frequent attacks may require radiofrequency ablation, in which the abnormally conducting tissue in the heart is destroyed. AVNRT occurs when a reentrant circuit forms within or just next to the atrioventricular node.
An automated external defibrillator or automatic electronic defibrillator (AED) is a portable electronic device that automatically diagnoses the life-threatening cardiac arrhythmias of ventricular fibrillation (VF) and pulseless ventricular tachycardia, [1] and is able to treat them through defibrillation, the application of electricity which stops the arrhythmia, allowing the heart to re ...
