Abstract:
A circuit for limiting leakage currents in a defibrillator having first and second circuit nodes for being coupled to a patient, comprising:(a) a first branch coupled to the first circuit node configured to conduct current from the first circuit node when the defibrillator is not generating a multiphasic defibrillation pulse; and (b) a second branch coupled to the second circuit node configured to conduct current from the second circuit node when the defibrillator is not generating a multiphasic defibrillation pulse, the first and second branches conducting current from the first and second nodes so as to reduce the voltage potential across the first and second nodes and thereby reduce leakage currents conducted to the patient; wherein the first and second branches each comprise two resistors in series, the branches being coupled to the circuit nodes at the node between the two resistors.
