Method for determining parameter values of an implanted programmable pacemaker
First Claim
Patent Images
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.

Abstract
In order to determine parameter values of an implanted programmable pacemaker, each parameter value is assigned a time ΔT which is a fraction of the pacing period T in the magnetic mode. In a pair of successive pacing intervals with the combined duration of 2T, one interval is shortened and the other lengthened by the amount ΔT. With the pacemaker in the magnetic mode, the parameter value is identified by observing the position of the middle pulse in the double interval 2T.
