Abstract
Abstract An electrode arrangement for a cardiac defibrillator includes one or more physiological sensors disposed in an electrode carrier for planar application against the exterior of the heart. The sensor contained in the electrode carrier is connected to a housing, containing a defibrillation power source and signal processing circuitry, via a sensor line, and the electrical signals obtained from the sensor are used for controlling operation of the defibrillator.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
135 words
An electrode arrangement for a defibrillator system comprising: an electrode adapted to deliver therapeutic electrical energy to a heart; a carrier containing and exposing said electrode at one side of said carrier adapted for placement against the exterior of the heart with said electrode in direct contact with the heart exterior; a source for said therapeutic electrical energy; an electrode line electrically connecting said electrode to said source of therapeutic electrical energy; sensor means for non-invasively measuring a physiologic function related to cardiac activity integrated in said electrode carrier and exposed for direct planar placement against the heart exterior; a sensor line connected to said sensor means; and means connected to said sensor line and to said source of therapeutic electrical energy for controlling delivery of said therapeutic electrical energy based on said physiologic function.
Claim 2
Dependent Claim
