1. A method for operating a cardiac rhythm management device, comprising:

  • delivering pacing pulses to a selected ventricular myocardial site;

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

    switching from a normal operating mode to a stress augmentation mode in which a particular region or regions of the ventricular myocardium are subjected to increased mechanical stress as compared with the stress experienced by those regions during the normal operating mode; and

    ,switching to the stress augmentation mode upon expiration of a timer, where the timer is defined with an expiration which coincides with when the patient is expected to awaken from sleep, and to cease operating in the stress augmentation mode upon expiration of a specified time period.
