1. A method of determining the values of the programmable parameters of an implanted programmable pacemaker, comprising:

  • operating the pacemaker in asynchronous mode with a pacing period T;

    assigning to each parameter value a time Δ

    T which is a fraction of the period T;

    in a pair of successive pacing intervals with the combined duration of 2T shortening one interval and lengthening the other by the amount Δ

    T; and

    comparing the relative lengths of said intervals, thereby identifying the parameter value.
