ABSTRACT:
Method and apparatus are provided for cardiac defibrillation using a waveform with a dominant frequency near that of a fibrillating heart. The defibrillator includes electrical generating means for producing a waveform having a dominant frequency within a range of 2 Hz-20 Hz. The waveform provides low level electrical shock to a fibrillating heart, thereby causing defibrillation. The waveform, which can comprise a Rossler-type chaotic waveform or a sinusoidal waveform, preferably has a dominant frequency near the frequency of fibrillation of the fibrillating heart.
