Abstract
Systems and methods facilitate placement of a lead in or on a patient's heart. At least one reference sensor is positioned at a right heart location of a patient's heart and a cardiac lead apparatus comprising at least one lead apparatus sensor is advanced to a plurality of left heart locations. Using the reference sensor and the lead apparatus sensor, a distance parameter indicative of a distance between the reference and lead apparatus sensors is measured for each of the plurality of left heart locations. Strain or stress estimates are determined for the plurality of left heart locations derived from the distance parameter measurements. Using the strain or stress estimates, a physician perceivable output is produced indicating suitability of the left heart locations as pacing sites.
