Abstract
An implantable cardiac stimulation device capable of delivering ESS, monitoring for myocardial ischemia and responding to the detection of myocardial ischemia by modifying the delivery of ESS. Modification of ESS delivery may include disabling ESS, initiating ESS, and/or modifying ESS control parameters.

4. A method of adapting an extra-systolic stimulation (ESS) therapy delivery sequence in response to an ischemia monitors output signal, comprising:
-
monitoring a volume of myocardial tissue for a myocardial ischemic condition and providing an output signal related to a presence or an absence of a myocardial ischemia condition;
in the event that the output signal indicates the presence of the myocardial ischemic condition and an ESS therapy is presently being applied to the volume of myocardial tissue, at least temporarily ceasing further delivery of the ESS therapy; and
in the event that the output signal indicates the presence of the myocardial ischemic condition and the ESS therapy is not presently being applied to the volume of myocardial tissue, initiating delivery of the ESS therapy. - View Dependent Claims (5, 6, 7, 8, 9, 10)

11. A computer readable medium for storing executable instructions for performing a method, comprising:
-
instructions for monitoring a volume of myocardial tissue for a myocardial ischemic condition and providing an output signal related to a presence or an absence of a myocardial ischemia condition;
in the event that the output signal indicates the presence of the myocardial ischemic condition and an ESS therapy is presently being applied to the volume of myocardial tissue, instructions for at least temporarily ceasing further delivery of the ESS therapy; and
in the event that the output signal indicates the presence of the myocardial ischemic condition and the ESS therapy is not presently being applied to the volume of myocardial tissue, instructions for initiating delivery of the ESS therapy. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. An apparatus for providing an adaptable extra-systolic stimulation (ESS) therapy delivery sequence in response to an output signal from a myocardial ischemia monitor, comprising:
-
means for monitoring a volume of myocardial tissue for a myocardial ischemic condition and providing an output signal related to a presence or an absence of a myocardial ischemia condition;
means for, in the event that the output signal indicates the presence of the myocardial ischemic condition and an ESS therapy is presently being applied to the volume of myocardial tissue, at least temporarily ceasing further delivery of the ESS therapy; and
means for, in the event that the output signal indicates the presence of the myocardial ischemic condition and the ESS therapy is not presently being applied to the volume of myocardial tissue, initiating delivery of the ESS therapy. - View Dependent Claims (19, 20, 21, 22, 23, 24)
