Method and apparatus for minimizing post-infarct ventricular remodeling
First Claim
Patent Images
1. A method for minimizing post-infarct ventricular remodeling, comprising:
- identifying an infarcted area in a ventricle;
delivering pacing pulses to one or more sites in proximity to the infarcted area; and
, wherein the pacing pulses are delivered in a manner that pre-excites the site or sites in proximity to the infarcted area relative to other areas of the ventricle.

Abstract
A cardiac rhythm management device for in which pre-excitation pacing is applied to one or more sites in proximity to an infarcted region of the ventricular myocardium. Such pacing servers to either prevent or minimize post-infarct remodeling.

15. A cardiac rhythm management device for delivering pre-excitation pacing therapy to minimize post-infarct ventricular remodeling, comprising:
-
one or more sensing channels for sensing intrinsic cardiac activity;
a plurality of pacing channels for delivering pacing pulses;
a controller for controlling the delivery of pacing pulses in accordance with a pacing mode;
a patch having incorporated therein a plurality of pacing electrodes incorporated into the pacing channels, the electrodes located on the periphery of the patch so as to circumscribe an infarct region when the patch is placed thereon. - View Dependent Claims (16, 17, 18)
