A method of predicting onset of electromechanical dissociation in a heart of a subject is disclosed. The method comprises: extracting from the composite input signal an electrocardiac signal and determining electrical activity of the heart based on the electrocardiac signal; extracting from the composite input signal a radiofrequency signal and determining blood flow measure based on the radiofrequency signal; and if the blood flow measure is below a predetermined threshold and the electrical activity is above a predetermined threshold, then predicting the onset of electromechanical dissociation.

La présente invention concerne un procédé permettant de prévoir le début d'une dissociation électrochimique dans le cAEur d'un sujet. Le procédé consiste à : extraire du signal d'entrée composite un signal électrocardiaque et déterminer une activité électrique du cAEur à partir du signal électrocardiaque; extraire du signal d'entrée composite un signal de radiofréquence et déterminer la mesure du débit sanguin à partir du signal de radiofréquence; et si la mesure du débit sanguin est inférieure à un seuil prédéterminé et l'activité électrique est supérieure à un seuil prédéterminé, prévoir alors le début de la dissociation électrochimique.
