Abstract

The present invention involves approaches for selecting one or more electrode combinations. Various method embodiments can include 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, delivering electrical stimulation to the patient's heart using the plurality of cardiac electrodes and the analyzer circuit, 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, selecting one or more electrode combinations of the plurality of cardiac electrodes based on the evaluation, and 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.

Dependent claims

A method for programming an implantable CRM device using an external programmer that has a display, wherein the CRM device includes an implantable lead having two or more electrodes, and wherein the CRM device is capable of selecting an electrode combination from a plurality of electrode combinations for use during therapy, the method comprising:

establishing communication between the implantable CRM device and the external programmer;
measuring or estimating a number of parameter values for each of two or more of the electrode combinations, wherein the number of parameter values include:
a value related to a capture threshold for the corresponding electrode combination;
a value indicative of battery consumption for the corresponding electrode combination, wherein the battery consumption corresponds to the measured or estimated value related to the capture threshold of the corresponding electrode combination;
a value related to an impedance for the corresponding electrode combination;
and
a value related to phrenic nerve stimulation for the corresponding electrode combination;
and
displaying on the display of the external programmer a table that includes, for each of at least two of the two or more electrode combinations, the value related to the capture threshold, the value indicative of the battery consumption, the value related to the impedance, and the value related to phrenic nerve stimulation;
selecting an electrode combination for therapy based, at least in part, on the table;
and
uploading the selected electrode combination to the CRM device.

a value related to a measured or estimated capture threshold for the corresponding electrode combination;
a value indicative of battery consumption for the corresponding electrode combination, wherein the value indicative of the battery consumption corresponds to the measured or estimated capture threshold for the corresponding electrode combination, and the value indicative of the battery consumption for the corresponding electrode combination is different from a value indicative of the battery consumption for at least one other of the plurality of electrode combinations;
a value related to an impedance for the corresponding electrode combination;
and
a value related to phrenic nerve stimulation for the corresponding electrode combination;
and
simultaneously display on the display of the user interface the value related to the capture threshold, the value indicative of the battery consumption, the value related to the impedance, and the value related to phrenic nerve stimulation for each of at least two of the two or more electrode combinations;
allow a user to select an electrode combination via the user interface based, at least in part, on the values of the number of parameters;
and
upload the selected electrode combination to the CRM device via the I/O unit.
