Implantable cardioverter defibrillator with slew rate limiting

摘要

The present invention is a pectorally implantable defibrillation system for delivering at least one electrical cardioversion/defibrillation countershock. The system has a housing designed to be implanted in a human patient, wherein the housing has an outer shell and an inner cavity. Pulse generating circuitry is positioned within the cavity for generating the at least one countershock. Circuitry is also positioned within the cavity to control delivery of the at least one countershock. A slew rate limiting circuit is connected between the pulse generating circuitry and one of a plurality of implantable electrodes so as to reduce a slew rate of the electrical countershock. Preferably, one of the implantable electrodes is the housing.
