Cardioversion is performed when the heart is beating ineffectively – either too fast or irregularly – in patients with atrial fibrillation or atrial flutter. It’s usually scheduled in advance but is sometimes also done in emergency situations. It can be done using an electric shock or with drugs.
Cardioversion is usually done with electric shocks, administered through electrodes attached to the chest, while the patient is sedated.
