Abstract:
1. A method of identifying treatment therapies as therapeutic strategies for preventing ventricular tachycardia from developing into ventricular fibrillation, said method comprising: detecting ventricular tachycardia in a subject; monitoring intervals between electrical stimuli in the heart of the subject; determining 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 identifying treatment therapies which prevent occurrence of a fourth stimuli corresponding to the rest interval values; and identifying treatment therapies which prevent said ventricular tachycardia from becoming ventricular fibrillation as therapeutic strategies for prevention of ventricular fibrillation, wherein said detecting, monitoring, determining and identifying are performed with an implantable medical device.
