This is a human outcome study for out-of-hospital cardiac arrest that looked at initial rhythm, basic life support treatment, and ventricular fibrillation waveform amplitude and frequency to predict defibrillation outcome. Changes in ventricular fibrillation waveform were monitored over the course of cardiac arrest.

Ann Emerg Med 2002, 40:563-574. This animal study evaluated ventricular fibrillation waveform changes in amplitude and median frequency, with and without CPR, and before defibrillation attempts. The ability of median frequency to predict outcome from defibrillation was reported.
