Abstract

The implantable pacing lead comprises a tip electrode for stimulating heart events and a sensor for sensing a physiological parameter, said sensor outputting a sensor signal, whereby the sensor is electrically connected to said tip electrode and adapted to be electrically connected to said body tissue. The lead further comprises switching means which is electrically connected between said sensor and said tip electrode. The switching means function as a short-circuit when stimulating heart events and as a break when sensing said physiological parameter. It is the purpose of the switching means to prevent a short circuit between the sensor and the tip electrode when measuring the sensor output signal and this is achieved by letting the switching means implement a high impedance circuit between the sensor and the tip electrode for low voltages and a low impedance circuit for high voltages.
