Therapy optimization via multi-dimensional mapping

TL;DR: In this paper, an exemplary method for accessing cardiac information acquired via a catheter located at various positions in a venous network of a patient where the cardiac information comprises position information, electrical information and mechanical information was presented.

Abstract: An exemplary method includes accessing cardiac information acquired via a catheter located at various positions in a venous network of a heart of a patient where the cardiac information comprises position information, electrical information and mechanical information; mapping local electrical activation times to anatomic positions to generate an electrical activation time map; mapping local mechanical activation times to anatomic positions to generate a mechanical activation time map; generating an electromechanical delay map by subtracting local electrical activation times from corresponding local mechanical activation times; and rendering at least the electromechanical delay map to a display Various other methods, devices, systems, etc, are also disclosed
