First Claim
Patent Images
1. A method, comprising:
- identifying a patient who may benefit from a stress induced cardioprotective effect;
implanting a device that includes a pacing channel for delivering pacing pulses to a selected ventricular myocardial site and a controller for controlling the delivery of pacing pulses in accordance with a programmed pacing mode; and
, programming the controller to intermittently switch 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.

Abstract
A device and method for delivering electrical stimulation to the heart in a manner which provides a protective effect is disclosed. The protective effect is produced by configuring a cardiac pacing device to intermittently switch from a normal operating mode to a stress augmentation mode in which the spatial pattern of depolarization is varied to thereby subject a particular region or regions of the ventricular myocardium to increased mechanical stress.
