BRADYCARDIA PACING IN A SUBCUTANEOUS DEVICE
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; and
if so, applying a series of 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;
wherein the series of pacing pulses is applied at a pacing rate that is faster than the predetermined level.

Abstract
A power supply for an implantable cardioverter-defibrillator for subcutaneous positioning between the third rib and the twelfth rib and using a lead system that does not directly contact a patient'"'"'s heart or reside in the intrathoracic blood vessels and for providing anti-bradycardia pacing energy to the heart, comprising 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.
