Method and apparatus for detecting myocardial ischemia
First Claim
1. A method for detecting myocardial ischemia in a subject comprising the steps of:
- monitoring the systemic vascular resistance of the subject; and
detecting the presence of myocardial ischemia in a subject when the monitored systemic vascular resistance of the subject increases by at least 60%, thereby indicating the presence of myocardial ischemia.

Abstract
An apparatus and method for detecting myocardial ischemia in a subject monitors the systemic vascular resistance of the subject and detects the presence of myocardial ischemia when the systemic vascular resistance increases by at least sixty percent over a base line value. Particular apparatus describe providing a measurement corresponding to the systemic vascular resistance of the cardiovascular system. A particular invasive pressure measuring apparatus uses a flexible catheter tube insertable into the artery of the subject and a micro-manometer embedded into the outer face of the wall of the catheter tube. The outer face of the embedded micro-manometer is directly exposed to the blood in an artery and the inner face of the embedded micro-manometer is covered by the inner face of the catheter tube wall.
