First Claim
1. A method for selecting at least one cardiac pacing site, the method comprising:
- directing a first elongate lead to a position along a portion of a right ventricular heart wall, the first lead including an electromagnetic receiver coil;
securing the electromagnetic receiver coil of the first lead at the position along the right ventricular heart wall;
inducing a signal in the electromagnetic receiver coil of the first lead by generating a magnetic field, the signal facilitating creation of a virtual representation of a portion of the first lead to direct the first lead to the first position, and to track wall motion at the position along the right ventricular heart wall;
directing a second elongate lead to a position along a left ventricular heart wall, the second lead including an electromagnetic receiver coil;
securing the electromagnetic receiver coil of the second lead at the position along the left ventricular heart wall;
inducing a signal in the electromagnetic receiver coil of the second lead by generating a magnetic field, the signal facilitating creation of a virtual representation of a portion of the second lead, in order to direct the second lead to the second position, and to track wall motion at the position along the left ventricular heart wall;
collecting a set of non-paced heart wall motion data from the signal of each of the electromagnetic receiver coils secured at the corresponding position;
applying cardiac pacing stimulation at an at least one first cardiac pacing site;
collecting a first set of paced heart wall motion data from the signal of each of the electromagnetic receiver coils secured at the corresponding position;
comparing the set of non-paced heart wall motion data to the first set of paced heart wall motion data; and
determining, based on the comparing, whether to maintain pacing at the at least one first cardiac pacing site or to apply pacing stimulation at a second cardiac pacing site for collection of a second set of paced heart wall motion data.

Abstract
A method for selecting a cardiac pacing site includes steps of: securing first and second electromagnetic receiver coils at first and second positions, respectively, along a heart wall; collecting a set of non-paced heart wall motion data from each of the coils secured at the corresponding positions; applying cardiac pacing stimulation at at least one first pacing site; collecting a first set of paced heart wall motion data from each of the secured coils; comparing the non-paced heart wall motion data to the first set of paced heart wall motion data; and determining, based on the comparing, whether to maintain pacing at the at least one first cardiac pacing site or to apply pacing stimulation at a second pacing site for collection of a second set of paced heart wall motion data. The at least one first pacing site may include a right ventricular site and a left ventricular site.
