Techniques for predicting and treating refractory ventricular fibrillation

Abstract

An example method includes identifying a first segment of an electrocardiogram (ECG) that ends prior to administration of an electrical shock and identifying at least one second segment of the ECG that begins after the administration of the electrical shock. The example method further includes predicting, based on the first segment and the at least one second segment, that the ECG is indicative of a defibrillation-resistant heart rhythm. The first segment is converted into a first scalogram, and the at least one segment is converted into at least one second scalogram. The defibrillation-resistant heart rhythm is predicted based on comparisons between the scalograms and the eigenscalograms. An indication of the predicted defibrillation-resistant heart rhythm is output.
