Site reversion in cardiac rhythm management
First Claim
1. A cardiac rhythm management system, comprising:
- a signal generator;
a first electrode adapted for connection to the signal generator;
a second electrode adapted for connection to the signal generator; and
a processor coupled to the signal generator, wherein the processor is adapted to cause the signal generator to deliver a first therapy to the first electrode in a first chamber, and to deliver a second therapy to the second electrode in a second chamber in the presence of a failure associated with the first electrode.

Abstract
Methods for failure recovery in a cardiac rhythm management system and apparatus capable of carrying out the methods. The methods include applying a first pacing therapy using one or more leads. The methods further include detecting a failure condition on one or more of the leads, wherein the failure condition prohibits or frustrates application of the first pacing therapy. The methods still further include applying a second pacing therapy using one or more of the leads subsequent to detecting the failure condition. The second pacing therapy is preferably chosen such that the detected failure does not interfere with the second pacing therapy. The second pacing therapy may be applied for only one cardiac cycle. The second pacing therapy may further be applied continuously until the failure condition is resolved, or it may be latched such that physician intervention is required to resume the first pacing therapy.

11. A cardiac rhythm management system, comprising:
-
a first lead having at least one electrode;
a second lead having at least one electrode;
a signal generator for producing pulses to apply through the first and second leads; and
a processor coupled to the signal generator, wherein the processor is adapted to cause the signal generator to deliver a first therapy through the at least one electrode of the first lead in a first chamber, and to deliver a second therapy through the at least one electrode of the second lead in a second chamber in the presence of a failure detection associated with the first lead. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
