Patent

CA 2747057

The present invention relates to advanced signal processing methods including digital wavelet transformation to analyze heart-related electronic signals and extract features that can accurately identify various states of the cardiovascular system. The invention may be utilized to estimate the extent of blood volume loss, distinguish blood volume loss from physiological activities associated with exercise, and predict the presence and extent of cardiovascular disease in general.

La présente invention concerne des procédés avancés de traitement des signaux intégrant une transformation en ondelettes numérique pour analyser les signaux électroniques associés au cur et extraire des caractéristiques pouvant identifier avec précision différents états du système cardiovasculaire. L'invention peut être utilisée pour évaluer l'ampleur d'une perte de volume sanguin, distinguer la perte de volume sanguin d'activités physiologiques associées à l'exercice, et prédire la présence et l'étendue d'une maladie cardiovasculaire en général.
