Abstract
Approaches for selecting an electrode combination of multi-electrode pacing devices are described. Electrode combination parameters that support cardiac function consistent with a prescribed therapy are evaluated for each of a plurality of electrode combinations. Electrode combination parameters that do not support cardiac function are evaluated for each of the plurality of electrode combinations. An order is determined for the electrode combinations based on the parameter evaluations. An electrode combination is selected based on the order, and therapy is delivered using the selected electrode combination.
Claims15
A cardiac rhythm management system, comprising:
- a plurality of electrode combinations comprising a plurality of cardiac electrodes;
- circuitry configured to evaluate, for each electrode combination of the plurality of electrode combinations, one or more first parameters associated with electrical stimulation delivered using the electrode combination, the first parameters supportive of cardiac function consistent with a prescribed cardiac resynchronization therapy (CRT);
- circuitry configured to evaluate, for each electrode combination of the plurality of electrode combinations, one or more second parameters associated with the electrical stimulation delivered using the electrode combination, the second parameters not supportive of cardiac function consistent with the prescribed CRT;
- an electrode combination processor configured to determine an order for at least some of the electrode combinations of the plurality of electrode combinations based on the evaluations of the first parameters and of the second parameters;
- and
- a therapy circuit configured to deliver CRT using a first electrode combination of the plurality of electrode combinations.
A system for selecting an electrode combination, the system comprising:
- a plurality of electrode combinations comprising a plurality of cardiac electrodes attached to an implantable housing;
- circuitry configured to evaluate, for each electrode combination of the plurality of electrode combinations, one or more first parameters associated with electrical stimulation delivered using the electrode combination, the first parameters supportive of cardiac function consistent with a prescribed cardiac resynchronization therapy (CRT);
- circuitry configured to evaluate, for each electrode combination of the plurality of electrode combinations, one or more second parameters associated with the electrical stimulation delivered using the electrode combination, the second parameters not supportive of cardiac function consistent with the prescribed CRT;
- means for determining an order for at least some of the electrode combinations of the plurality of electrode combinations based on the evaluations of the first parameters and of the second parameters;
- and
- a therapy circuit configured to deliver CRT using at least one of the electrode combinations of the plurality of electrode combinations.
