  • Protective circuit
    Patent number: 5170806
    Abstract: For the purpose of improving the interference resistance capability of a therapeutically and/or diagnostically operational unit, specifically of a cardiac pacemaker with an input circuit and an output circuit, a decoupling circuit is provided. The decoupling circuit allows the output circuit to be decoupled from the terminal connector pair of the unit. The decoupling of the asymmetrically limiting output circuit always occurs independent of the presence of possible interfering signals for the entire duration of the impulse period.
