Abstract
Abstract An implantable defibrillator comprising a first implantable energy source connected to an implantable monitoring circuit means and a second implantable energy source having a predetermined different energy output than said first implantable energy source connected to an implantable inverter/output circuit means. The implantable monitoring circuit is powered by the first implantable energy source and the implantable inverter/output circuit is powered by the second implantable energy source.
