Abstract
A system for facilitating placement of a lead in or on a patient's heart includes a first lead apparatus, a second lead apparatus, a user interface, and a processor. The processor is configured to measure a distance parameter indicative of a distance between a reference sensor element at a right heart location and a lead apparatus sensor element at each of a plurality of left heart locations in either the left ventricle or a coronary venous pathway, determine a separation distance for each of the plurality of left heart locations from the right heart location based on the distance parameter measurements, and determine that the separation distance for a location of the plurality of left heart locations from the right heart location is less than a threshold distance based on the separation distance for the location. The threshold distance representative of unsuitability for pacing.
