1. A cardiac rhythm management device, comprising:

  • sensing channels for sensing cardiac electrical activity at a plurality of myocardial sites;

    pacing channels for delivering pacing pulses to one or more myocardial sites;

    a controller for controlling the delivery of pacing pulses in accordance with a programmed pacing mode;

    circuitry for measuring activation-recovery intervals at a plurality of myocardial sites indicative of myocardial wall stress; and

    , circuitry for identifying one or more stressed myocardial sites based upon the measured activation-recovery intervals.
