Systems and methods for facilitating selecting of one or more vectors in a medical device
First Claim
1. A method of facilitating selection of a vector for delivering electrical stimulation to a patient'"'"'s heart via an electro-stimulation device having three or more electro-stimulation electrodes using a device-based cardiac capture threshold test, the method comprising:
- displaying a plurality of vectors on a display screen, wherein each vector represents a different combination of the three or more electro-stimulation electrodes;
measuring an electrical pacing impedance for each of the plurality of vectors using the electro-stimulation electrodes;
displaying on the display screen the measured electrical pacing impedance for each of the plurality of vectors;
receiving a selection of a set of the plurality of vectors as a selected first sub-set of the plurality of vectors in response to the displaying on the display screen the measured electrical pacing impedance for each of the plurality of vectors;
determining a capture threshold for each of the vectors of the first subset of the plurality of vectors;
displaying on the display screen the determined capture threshold for each of the vectors of the first subset of the plurality of vectors;
receiving a further selection of a vector from the received first subset of the plurality of vectors, in response to the displaying on the display screen the determined capture threshold, for delivery of electrical stimulation to the patient'"'"'s heart; and
programming the electro-stimulation device to use the selected vector when delivering electrical stimulation to the patient'"'"'s heart.

Abstract
Some systems and methods may facilitate selection of a vector for delivering electrical stimulation to a patient'"'"'s heart. One method may include displaying a plurality of vectors on a display screen wherein each vector represents a different combination of three or more electro-stimulation electrodes, determining an electrical impedance for each of the plurality of vectors, displaying on the display screen the electrical impedance for each of the plurality of vectors, receiving a selection of a set of the plurality of vectors, determining, for each of the vectors in the set of vectors, a capture threshold, displaying on the display screen the capture threshold for each of the vectors in the set of vectors, receiving a selection of a vector from the set of vectors for delivery of electrical stimulation to the patient'"'"'s heart, and programming the electro-stimulation device electrical stimulation to the patient'"'"'s heart via the selected vector.
