Methods and systems for use in selecting cardiac pacing sites

A non-transitory computer-readable medium having stored thereon at least one instruction that, when executed by a computer, causes the computer to:

• receive non-paced heart wall motion data representative of the motion of first and second sensors of first and second elongate leads secured at corresponding first and second positions along a right ventricular heart wall and a left ventricular heart wall, respectively;
• receive paced heart wall motion data representative of the motion of the first and second sensors secured at the first and second positions along the right ventricular heart wall and the left ventricular heart wall, respectively, when cardiac pacing stimulation is applied at one or more first pacing sites;
• generate data representative of a comparison of non-paced heart wall motion and paced heart wall motion based on at least a portion of the non-paced heart wall motion data and at least a portion of the paced heart wall motion data, wherein the image data representative of the comparison is indicative of the effectiveness of pacing at the one or more first pacing sites;
• and
• generate notification data indicative of the one or more first pacing sites being one of an optimal pacing site and a non-optimal pacing site.

A method for use in selecting at least one cardiac pacing site, the method comprising:

• introducing a first elongate lead to a position along a right ventricular heart wall, the first elongate lead including a first electromagnetic receiver coil;
• coupling the first electromagnetic receiver coil at a first position along the right ventricular heart wall;
• inducing a first signal in the first electromagnetic receiver coil by generating a magnetic field, the first signal facilitating creation of a first virtual representation of at least a portion of the first elongate lead to direct the first elongate lead to the first position, and to track wall motion along the right ventricular heart wall;
• introducing a second elongate lead to a second position along a left ventricular heart wall, the second elongate lead including a second electromagnetic receiver coil;
• coupling the second electromagnetic receiver coil at the second position along the left ventricular heart wall;
• inducing a second signal in the second electromagnetic receiver coil by generating a magnetic field, the second signal facilitating creation of a second virtual representation of at least a portion of the second elongate lead to direct the second elongate lead to the second position, and to track wall motion along the left ventricular heart wall;
• storing 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 one or more first pacing sites;
• collecting a 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 set of paced heart wall motion data;
• determining, based on the comparison, whether to maintain pacing at the one or more first pacing sites or to apply pacing stimulation at one or more second pacing sites for collection of a second set of paced heart wall motion data;
• generating notification data indicative of the one or more first pacing sites being one of an optimal pacing site and a non-optimal pacing site.

A method for use in selecting at least one cardiac pacing site, the method comprising:

• coupling a first sensor at a first position along a right ventricular heart wall, the first sensor configured to track wall motion of the heart wall;
• coupling a second sensor at a second position along a left ventricular heart wall, the second sensor configured to track motion of the heart wall,
• collecting non-paced heart wall motion data based on the location of the first and second sensor at the corresponding positions;
• applying cardiac pacing stimulation at one or more first pacing sites;
• collecting paced heart wall motion data based on the location of the first and second sensor at the corresponding positions when the cardiac pacing stimulation is applied;
• comparing the non-paced heart wall motion data to the paced heart wall motion data;
• generating image data, using an imaging device, representative of the comparison of non-paced heart wall motion data and paced heart wall motion data, wherein the image data representative of the comparison is indicative of the effectiveness of pacing at the one or more first pacing sites;
• and
• visualizing the image data representative of the comparison to assist a user in selecting a pacing site.
