| 摘要 |
The present invention involves approaches for selecting one or more electrode combinations. Various method embodiments can include means for implanting a plurality of cardiac electrodes supported by one or more leads in a patient, attaching the one or more leads to a patient external analyzer circuit, means for delivering electrical stimulation to the patient's heart using the plurality of cardiac electrodes and the analyzer circuit, means for evaluating, for each electrode combination of a plurality of electrode combinations of the plurality of cardiac electrodes, one or more first parameters and one or more second parameters produced by the electrical stimulation delivered using the electrode combination, the first parameters supportive of cardiac function consistent with a prescribed therapy and the second parameters not supportive of cardiac function consistent with the prescribed therapy, means for selecting one or more electrode combinations of the plurality of cardiac electrodes based on the evaluation, the one or more electrode combinations selected as being associated with the one or more first parameters and less associated with the one or more second parameters relative to other electrode combinations of the plurality of cardiac electrodes, means for programming an implantable pacing circuit to deliver a cardiac pacing therapy that preferentially uses the selected one or more electrode combinations relative to other electrode combinations of the plurality of cardiac electrodes, means for detaching the one or more leads from the analyzer circuit, means for attaching the one or more leads to the implantable pacing circuit, and means for implanting the implantable pacing circuit. |
