Intermittent stress augmentation pacing for cardioprotective effect
First Claim
Patent Images
1. A cardiac rhythm management device, comprising:
- a pulse generator for delivering pacing pulses to a selected ventricular myocardial site through a pacing channel;
a controller for controlling the delivery of pacing pulses in accordance with a programmed pacing mode,wherein the controller is programmed to operate in either a normal operating mode or 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
,wherein the controller is further programmed to intermittently switch from the normal operating mode to the stress augmentation mode for a specified stress augmentation time period according to a defined schedule.

Abstract
A device and method for delivering electrical stimulation to the heart in a manner which provides a protective effect against subsequent ischemia 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.
