A cardiac pacemaker for implanting in a patient includes a device for applying stimulating pulses to the heart of the patient at a rate determined by a pacing parameter; a plurality of devices for detecting a corresponding plurality of physiological parameters which are respectively associated with physical exertion of the patient and producing a corresponding plurality of output signals representative of the corresponding physiological parameters; a circuitry device receiving the first output signals for varying the pacing parameter as a function of the first output signal, an external programming device in communication with the circuitry device; a linking element in communication with the external programming devices which selectably links the circuitry device with a selectable one of the plurality of device for detecting; and the external programming device causing the linking element to select a given one of the plurality of detecting device for linking with the circuitry device.
