METHOD, APPARATUS AND SYSTEM FOR PREDICTING ELECTROMECHANICAL DISSOCIATION
First Claim
1. A method of predicting onset of electromechanical dissociation in a heart of a subject using a composite input electrical signal received from the subject, the method comprising:
- extracting from the composite input signal an electrocardiac signal and determining electrical activity of the heart based on said electrocardiac signal;
extracting from the composite input signal a radiofrequency signal and determining blood flow measure based on said radiofrequency signal; and
if said blood flow measure is below a predetermined threshold and said electrical activity is above a predetermined threshold, then predicting the onset of electromechanical dissociation.
