Abstract:
1. A system for use in identifying treatment therapies as therapeutic strategies for preventing ventricular tachycardia from developing into ventricular fibrillation, said system comprising: a medical device programmed to detect ventricular tachycardia in a subject; monitor intervals between electrical stimuli in the heart of the subject; determine if an initial 3 stimuli in groups of 4 stimuli from said monitoring in the heart correspond to rest interval values (I) predicted to lead to ventricular fibrillation as defined by a first equation as follows:  wherein τ is a time interval between activations applied to a pacing site (x identify treatment therapies which prevent occurrence of a fourth stimuli corresponding to the rest interval values; and identify treatment therapies which prevent said ventricular tachycardia from becoming ventricular fibrillation as therapeutic strategies for prevention of ventricular fibrillation.
