Implantable defibrillator system and method having successive changeable defibrillation waveforms

摘要

An implantable defibrillator having programmable shock waveforms and paths where each successive waveform may be of a different shape and form, and delivered to and through an area of the human heart in a desired sequence. The shock waveforms can be delivered independently through certain areas of the heart or through different areas of the heart to the can electrode or to a patch electrode at a computed common time. Alternatively, a first shock waveform or set of shock waveforms can be delivered through one or more areas of the heart followed by a delivery of time sequenced delayed shock waveform or forms through specific areas of the heart to the can electrode or patch electrode.
