Abstract
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.

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 a future onset of electromechanical dissociation.
Apparatus for predicting onset of electromechanical dissociation in a heart of a subject, the apparatus comprising:
- an input unit for receiving a composite input electrical signal from the subject;
- an electrocardiac unit for extracting from the composite input signal an electrocardiac signal and determining electrical activity of the heart based on said electrocardiac signal;
- a radiofrequency unit for extracting a radiofrequency signal from the composite input signal and determining blood flow measure based on said radiofrequency signal;
- and
- an output unit for outputting a signal predicting a future onset of electromechanical dissociation if said blood flow measure is below a predetermined threshold and said electrical and activity is above a predetermined threshold.
