Abstract

Apparatus for transcutaneously pacing and defibrillating the heart of a patient, having defibrillation pulse discharge circuitry 30 and pacing stimuli generator circuitry 42, both circuits having positive and negative connections 40A, 40B, and 46A, 46B; and including a first multipin connector 49 having four pins at each of which one of the four connections is supplied; a second multipin connector 53 configured to mate with the first multipin connector, and having internal connections to electrically connect the positive connections for the pacing and defibrillation circuitry 40A, 46A and likewise connecting the negative connections of the pacing and defibrillation circuitry 40B, 46B, wherein the positive and negative multifunction connections 58A, 58B are suited for connecting to multifunction electrodes through which both pacing stimuli and defibrillation pulses may be supplied; and a third multipin connector 12 also configured to mate with the first connector, but configured to isolate the pacing connections from the defibrillation connections, thereby providing pacing stimuli outputs 16 suitable for connecting to pacing electrodes and defibrillating pulse outputs 14 suitable for connecting to separate defibrillation electrodes. The second and third connectors are configured so that they may be alternately connected to the first connector without any adaptation of the first connector or the circuitry.
