ABSTRACT:
Apparatus for providing a solid state patient isolator circuit capable of conducting bipolar portions of a biphasic defibrillation pulse when the isolator circuit is ON and further capable of isolating circuitry upstream or downstream of the patient isolator when the isolator circuit is OFF. The apparatus includes series connected solid state switching devices having a resistor ladder connected in parallel therewith to balance voltages across the solid state switching devices when the devices are OFF. The solid state switching devices are selected from among the group of uni-directionally conducting solid state switches and are connected between the intermediate nodes of a four diode bridge having an input node and an output node.
