ABSTRACT:
A single paddle is capable of delivering pacing and defibrillating electrical pulses to a patient. In one embodiment, the paddle has a region of high electrical conductivity coupled to a defibrillating electrode for delivering defibrillating pulses. The paddle also includes a region of low electrical conductivity coupled to a pacing electrode for delivery pacing pulses. In an alternative configuration, a region of high electrical conductivity is sandwiched between regions of low electrical conductivity. The regions are comprised of polymeric gel or gel-filled foam.
