1. An implantable cardiac stimulation device having pulse generating means for delivering stimulation pulses to the heart of a patient, the device comprising:

  • measuring means for measuring a parameter having a volatile value which varies over time relating to the delivery of therapeutic electrical stimulation, and for providing an output signal representative thereof; and

    processing means for triggering the measuring means to measure the output signals at a variable rate, wherein the processing means determines the variable rate based on a comparison between a current output signal and a previous output signal so that the output signal is measured at a greater frequency when the parameter value is volatile and at a lesser frequency when the parameter value remains stable.
