Body activity sensors, such as termperature, motion, respiration and/or blood oxygen sensors, are positioned in a patient\s body outside the pacer capsule. These sensors wirelessly transmit body activity signals, which are processed by circuitry in the heart pacer, such that a stimulation pulse generator within the pacer capsule is controlled by the body activity signals. Preferably, the transmission between the sensors and the capsule is two-way, thereby allowing the sensors to receive control signals for altering the sensor characteristics.
