Monitor for early detection of ischemic heart disease
First Claim
Patent Images
1. A monitor for early detection of an ischemic heart disease, comprising:
- an impedance measurement unit, including an electrode arrangement for interacting with a patient to measure an intracardiac impedance and to generate a corresponding impedance signal;
a notch detector connected to said impedance measurement unit which detects an occurrence of a notch in the impedance signal coincident with entry of blood into a ventricle, with a portion of said impedance signal following said notch being a post-notch impedance curve; and
a pattern recognition unit, which compares said post-notch impedance curve with a stored reference impedance curve template to obtain a comparison result and to detect an ischemic heart disease from said comparison result.

Abstract
A monitor for early detection of an ischemic heart disease of a patient has an impedance measurement unit including an electrode arrangement for measuring an intracardiac impedance and generating a corresponding impedance signal, a notch detector connected to the impedance measurement unit for detecting the occurrence of a notch in the impedance signal coincident with the entry of blood into the ventricle, and a pattern recognition unit which compares the measured post-notch impedance curve with a stored predetermined reference impedance curve template to detect an ischemic heart disease from the result of the comparison.
