Therapy optimization via multi-dimensional mapping
First Claim
1. A method comprising:
- accessing cardiac information acquired via a catheter located at various positions in a venous network of a heart of a patient wherein the cardiac information comprises position information, electrical information and mechanical information;
for the various positions, mapping local electrical activation times to anatomic positions to generate an electrical activation time map, the electrical activation times based on the electrical information and the anatomic positions based on the position information;
for the various positions, mapping local mechanical activation times to anatomic positions to generate a mechanical activation time map, the mechanical activation times based on the mechanical information and the anatomic positions based on the position information;
transforming coordinates for the various positions to a non-cartesian coordinate system;
generating an electromechanical delay map by subtracting local electrical activation times from corresponding local mechanical activation times; and
rendering at least the electromechanical (EM) delay map to a display relative to the non-cartesian coordinate system.
