First Claim
Patent Images
1. A cardiac device, comprising:
- one or more sensing channels for sensing cardiac activity;
a therapy channel for delivering therapy to the heart;
a controller for controlling the delivery of therapy in response to the sensed cardiac activity; and
, wherein the controller is programmed to compute a composite ischemia function from two or more parameters associated with cardiac ischemia and to adjust the manner in which the therapy is delivered in accordance therewith.
