First Claim
Patent Images
1. A method of medically treating a person comprising:
- determining that a defibrillation stimulus has been applied to the person; and
, if so, determining whether a rate of cardiac events for the person is below a predetermined level; and
, if so, applying a series of pacing pulses to the person;
wherein the series of pacing pulses is applied 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.

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.

-
determining that a defibrillation stimulus has been applied to the person; and
, if so,determining whether a rate of cardiac events for the person is below a predetermined level; and
, if so,applying a series of pacing pulses to the person in response to the detected bradycardia;
wherein the pacing pulses are applied using subcutaneously located means for stimulating the heart. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A method of medically treating a person comprising:
-
providing cardiac pacing pulses to the person at a first rate, wherein the pacing pulses are provided between a first electrode disposed on a lead assembly of an implantable cardiac stimulus system and a second electrode disposed on a canister of the implantable cardiac stimulus system; and
modifying the first rate in response to a physiologic condition;
wherein the lead assembly is disposed subcutaneously over the ribs of the person. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26)
