Abstract:
1. An implantable medical device (IMD) comprising: an ischemia detection module for detecting cardiac ischemia or infarct in a region of cardiac tissue proximate a multiple-electrode lead, wherein the ischemia detection module is operable to evaluate intracardiac electrogram (IEGM) data from each electrode on the multiple-electrode lead to detect the relative proximity of the cardiac ischemia or infarct region from each electrode of the multiple electrode lead; and an electrode selection module coupled to the ischemia detection module, wherein the electrode selection module compares the relative proximity of each of the electrodes to the cardiac ischemia or infarct region and is adapted to select an electrode from the multiple-electrode lead that is relatively less proximate the cardiac ischemic or infarct region than another electrode of the multiple-electrode lead.
