Site reversion in cardiac rhythm management
First Claim
1. A method comprising:
- delivering one or more signals through at least a first electrode in a first pacing protocol for one or more first ventricular chambers of a heart;
monitoring detection of a first failure condition with the first electrode; and
invoking a second pacing protocol for one or more second ventricular chambers subsequent to detecting the first failure condition, including delivering one or more signals for the second pacing protocol.

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.

12. A cardiac rhythm management system, comprising:
-
a signal generator electrically coupled with a first electrode, the signal generator electrically coupled with a second electrode; and
a processor coupled with the signal generator, wherein the processor is adapted to cause the signal generator to deliver at least one first signal to a least one first ventricular chamber through at least one electrode in a first protocol, and to deliver at least one second signal to a least one second ventricular chamber through at least one electrode in a second protocol in response to a first failure condition detected with the first electrode. - View Dependent Claims (13, 14, 15, 16, 17)

18. A cardiac rhythm management system, comprising:
-
a signal generator electrically coupled with a first electrode, the signal generator electrically coupled with a second electrode, the first electrode disposed along a first lead, the second electrode disposed along a second lead; and
a processor coupled with the signal generator, wherein the processor causes the signal generator to deliver at least one first signal to a first ventricular chamber through at least the first electrode, and to deliver at least one second signal to a second chamber through the second electrode in response to a first failure condition associated with at least one of the first electrode or the first lead. - View Dependent Claims (19, 20, 21, 22)
