First Claim
Patent Images
1. A method of medically treating a person comprising:
- estimating the person'"'"'s cardiac rate;
determining whether the person'"'"'s cardiac rate is at or below a predetermined level;
if so, applying a series of electrical pacing pulses to the person between a first electrode disposed at a subcutaneous location over the person'"'"'s ribs as part of a lead assembly, and a second electrode disposed on a canister implanted in the person, the lead assembly being coupled to the canister; and
wherein the series of pacing pulses is applied at a pacing rate that is faster than the predetermined level, and the pacing pulses are applied via a totally subcutaneous, non-transvenous system.

Abstract
Methods of medically treating a patient by the use of anti-bradycardia pacing using a totally subcutaneous, non-transvenous system. Some examples include the application of pacing pulses to a patient at a pacing rate that is above a predetermined level. One example of a totally subcutaneous, non-transvenous system includes a capacitor subsystem for storing the anti-bradycardia pacing energy for delivery to the patient'"'"'s heart; and a battery subsystem electrically coupled to the capacitor subsystem for providing the anti-bradycardia pacing energy to the capacitor subsystem.

17. A method of medically treating a person comprising:
-
detecting that the person is likely experiencing an arrhythmia using totally subcutaneously, non-transvenously implanted cardiac stimulus system that does not directly contact the heart; and performing a step for stimulating the person'"'"'s heart to beat at a higher rate by applying electrical pacing stimuli using said cardiac stimulus system having a subcutaneously implanted electrode disposed on a lead assembly and an electrode disposed on a canister coupled to the lead assembly. - View Dependent Claims (18)
