1. A medical device, comprising:
a processor configured to:
identify a ventricular fibrillation (VF) cardiac event by analyzing an ECG signal of a patient;
generate a viability index by analyzing the VF cardiac event and a patient physiological parameter;
determine a classification of the VF cardiac event as a first VF type or a second VF type by analyzing the viability index;
in response to determining the classification of the VF cardiac event, determine a post-defibrillation shock treatment for the patient; and
output an instruction to perform the post-defibrillation shock treatment following delivery of a defibrillation shock to the patient.
