Systems and methods for ranking and selection of pacing vectors
First Claim
1. A method of programming a cardiac device, comprising:
- receiving input through a user interface, wherein the input is utilized for, at least in part, a selection of a plurality of cardiac electrodes for testing as potential Left Ventricular (LV) pacing vectors;
measuring a value of a parameter indicating hemodynamic function of pacing for the selected plurality of cardiac electrodes;
eliminating one or more cardiac electrodes from a set of viable cardiac electrodes according to the parameter indicating hemodynamic function, wherein further testing is performed only on the set of viable cardiac electrodes;
measuring one or both of a cardiac capture threshold and a phrenic nerve activation threshold for the set of viable cardiac electrodes; and
programming the cardiac device to deliver therapy using the LV pacing vectors based on the one or both measured cardiac capture threshold and phrenic nerve activation threshold.

Abstract
Approaches to rank potential left ventricular (LV) pacing vectors are described. Early elimination tests are performed to determine the viability of LV cathode electrodes. Some LV cathodes are eliminated from further testing based on the early elimination tests. LV cathodes identified as viable cathodes are tested further. Viable LV cathode electrodes are tested for hemodynamic efficacy. Cardiac capture and phrenic nerve activation thresholds are then measured for potential LV pacing vectors comprising a viable LV cathode electrode and an anode electrode. The potential LV pacing vectors are ranked based on one or more of the hemodynamic efficacy of the LV cathodes, the cardiac capture thresholds, and the phrenic nerve activation thresholds.
