METHOD AND APPARATUS FOR QUANTIFICATION AND MONITORING OF CARDIOVASCULAR FUNCTION DURING INDUCED STRESS OR PHYSICAL ACTIVITY AND AT REST
First Claim
1. Method for quantifying and monitoring cardiovascular function comprising continuous determination of significant individual cardiovascular function parameters through at least one, operator-independent platform during a sample period at rest, the method comprising:
- recording the data determined, continuously monitoring these data during pharmacological stress or exercise activity,comparing the memorized data with those determined during the same time span of the sample period and comparing the cardiovascular function changes occurring during stress or exercise vs rest, andcomparing the cardiovascular function changes occurring during recovery vs rest and vs. stress or exercise, the memorized parameters comprising at least one curve of a cardiovascular function selected from the group consisting of;
a systemic blood pressure-frequency relation, a force-frequency relation, a respiratory rate-frequency relation, a diastolic left ventricular active relaxation-frequency relation, a diastolic right ventricular active relaxation-frequency relation, a pulmonary artery pressure-frequency relation, an anaerobic threshold-frequency relation, a recovery contractility and a diastolic function overshoot-frequency relation, wherein the sensor is an accelerometer measuring the vibrations produced by the cardiovascular system and physiologically transferred from the inside of the body to the chest surface.

Abstract
Method and apparatus for the quantification and monitoring of cardiovascular function comprising continuous determination of significant individual cardiovascular function parameters through an operator-independent accelerometer during a sample period at rest, recording the data determined, continuously monitoring these data during pharmacological stress or exercise activity, comparing the memorized data with those determined during the same time span of the sample period and comparing the changes in cardiovascular function occurring during stress or exercise vs rest, and comparing the changes in cardiovascular function occurring during recovery vs rest and vs stress or exercise.
