MECHANISM FOR DETECTING CORONARY ISCHEMIA

摘要

A system for detecting myocardial ischemia includes an implantable device having one or more leads connected thereto, at least one electrode on a lead of the device, and a microprocessor in the implantable device. The electrode is configured to stimulate the heart. The at least one sensor is configured to measure a characteristic of blood in a coronary vessel. The microprocessor is programmed to: run a stress test on the heart by stimulating the heart with the electrode; record data obtained from the at least one sensor during the stress test; and determine whether there is myocardial ischemia based upon the recorded data.
