1. A method for operating a pacemaker with at least a first sensing channel and a second sensing channel, the method comprising:

  • operating the pacemaker in a programmed mode during which the first sensing channel is an active sensing channel and the second sensing channel is an inactive sensing channel not used for inhibiting or triggering any pacing pulse, the programming mode having a plurality of programmed states;

    initiating a passive measurement testing mode;

    transitioning from a current state of the plurality of programmed states to a lead impedance measuring test state;

    measuring a lead impedance associated with a lead of the second sensing channel during the lead impedance measuring test state;

    storing the measured lead impedance; and

    deactivating the passive measurement testing mode and returning to the current state of the plurality of programmed states after the measured lead impedance is stored.
