Patent ID: 7171269

Claim:
A method of decomposition of waveforms in a cardiac signal comprising the steps of: a) connecting electrodes to a patient whose heart is in Ventricular Fibrillation (VF); b) deriving analogue input signals from the electrodes; c) sampling said analogue input signals to derive the cardiac signal (EKG); d) digitising said EKG signal; e) employing wavelet transform analysis to process said digitised EKG signal; f) extracting key features from the wavelet transform representation to predict the outcome of a specific interim therapeutic intervention during the Ventricular Fibrillation; and g) guiding a resuscitation protocol based on the prediction, said guidance comprising the steps of; h) using an analytical method to determine the likely outcome of a defibrillation shock; and i) determining whether to provide at least one interim therapeutic intervention from a group comprising defibrillatory shock, CPR and pharmaceutical, before shocking.
