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.

displaying a plurality of vectors on a display screen, wherein each vector represents a different combination of the three or more electro-stimulation electrodes;

determining an electrical impedance for each of the plurality of vectors;

displaying on the display screen the determined 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 the plurality of vectors, a capture threshold;

displaying on the display screen the capture threshold for each of the vectors in the set of the plurality of vectors;

receiving a selection of a vector from the set of the plurality of vectors 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.

2. The method of claim 1, wherein after displaying the plurality of vectors on the display screen but before receiving the selection of the set of the plurality of vectors, the method further comprises:

determining an electrical delay for each of the plurality of vectors; and

displaying on the display screen the determined electrical delay and the determined electrical impedance for each of the plurality of vectors.

3. The method of claim 2, further comprising displaying on the display screen the determined electrical delay and the determined electrical impedance for each of the plurality of vectors in a table format, wherein the plurality of vectors are each represented in a row, and the determined electrical delay and the determined electrical impedance are represented in columns.

4. The method of claim 3, further comprising:

selecting a first column; and

sorting the table by the selected first column.

5. The method of claim 4, further comprising:

selecting a second column after selecting the first column; and

sorting the table by the first column, and then if duplicate entries exist in the first column, sorting the duplicate entries by the second column.

6. The method of claim 4, further comprising:

selecting one or more rows from the table that is sorted by the first column;

selecting a second column; and

sorting the selected rows by the selected second column.

7. The method of claim 1, further comprising determining a presence of phrenic nerve stimulation or not for at least a sub-set of the plurality of vectors, and displaying on the display screen the determined presence or not of phrenic nerve stimulation for each of the vectors.

8. The method of claim 7, further comprising sorting the plurality of vectors based on the presence of phrenic nerve.

9. The method of claim 1, wherein the set of the plurality of vectors is less than all of the plurality of vectors.

10. A system for facilitating selection of at least one vector for delivering electrical stimulation to a chamber of a patient'"'"'s heart, the system comprising:
