NON-INVASIVE MONITORING AND TREATMENT OF SUBJECTS IN CARDIAC ARREST USING ECG PARAMETERS PREDICTIVE OF OUTCOME

摘要

A method and apparatus for determining the metabolic state of the myocardium of a subject in ventricular fibrillation or asystole and/or for guiding therapeutic interventions. Electrocardiogram signals of the subject's heart are transformed to a frequency domain power spectrum, and at least one frequency parameter is monitored and processed to a value predictive of a clinically relevant cardiac arrest outcome. In the preferred embodiment, centroid frequency and/or peak power frequency of the power spectrum are monitored.
