[ de- + fibrillation ]

1. Termination of ventricular fibrillation (vfib) with electrical countershock(s). This is the single most important intervention a rescuer can take in patients who have suffered cardiac arrest due to vfib or pulseless ventricular tachycardia.

PATIENT CARE
To defibrillate a patient, power on the device, attach pads or paddles to the patient’s skin, charge the device, clear anyone from contact with it or with the electricity it will discharge, and then deliver a shock. Immediately resume chest compressions. Health care providers should become familiar with the defibrillators in their facility so they can rapidly operate them in an emergency. Staff development programs and course training can help ensure or maintain competent use.

2. A term formerly used to signify termination of atrial fibrillation. The contemporary terms are conversion or cardioversion.
