Overview
Patients with hemodynamic instability should undergo electrical cardioversion (also known as direct-current or DC cardioversion) and treatment with parenteral agents, to slow the heart rate.
Electrical Cardioversion
The following scenarios warrant urgent DC cardioversion:
- The presence of cardiogenic shock or hypotension.
- Decompensated heart failure.
- Refractory ischemia, ischemic EKG changes.

Rhythm Control
Direct-Current Cardioversion: Recommendations
| Class I |
| "1. In pursuing a rhythm-control strategy, cardioversion is recommended for patients with AF or atrial flutter as a method to restore sinus rhythm. If cardioversion is unsuccessful, repeated direct-current cardioversion attempts may be made after adjusting the location of the electrodes, applying pressure over the electrodes, or following administration of an antiarrhythmic medication. (Level of Evidence: B)" |
| "2. Cardioversion is recommended when a rapid ventricular response to AF or atrial flutter does not respond promptly to pharmacological therapies and contributes to ongoing myocardial ischemia, hypotension, or HF. (Level of Evidence: C)" |
| "3. Cardioversion is recommended for patients with AF or atrial flutter and pre-excitation when tachycardia is associated with hemodynamic instability. (Level of Evidence: C)" |
| Class IIa |
| "1. It is reasonable to perform repeated cardioversions in patients with persistent AF provided that sinus rhythm can be maintained for a clinically meaningful period between cardioversion procedures. Severity of AF symptoms and patient preference should be considered when embarking on a strategy requiring serial cardioversion procedures. (Level of Evidence: C)" |
