Claim:
1. A lead delivery system for delivering a lead to the bundle of His from below the tricuspid valve in the right ventricle, the delivery system comprising: an outer guide catheter having a proximal end, a distal end, a distal tip, a lumen having an opening at the distal tip of the outer guide catheter, and a preformed curve in the distal end of the outer guide catheter, the curve in the distal end of the outer guide catheter approximately 180 degrees, the outer guide catheter configured to be introduced transvascularly and extend down the superior vena cava and position the curve of the outer guide catheter within the right ventricle; an inner guide catheter having a proximal end, a distal end, a lumen having a opening on the distal end, at least one electrode on the distal end, at least one conductor extending from the electrode to the proximal end, and a curve in the distal end, the inner guide catheter moveable within the lumen of the outer guide catheter and extendable from the opening of the outer guide catheter, the curve in the distal end of the inner guide catheter dimensioned to point the opening of the lumen of the inner guide catheter at a target site in an area extending from immediately below the tricuspid valve in the right ventricle to about 15 millimeters down the septal wall proximate the bundle of His when the curve of the outer guide catheter is within the right ventricle and the curve of the inner guide catheter is extended out of the lumen of the outer guide catheter; an anchor wire having a proximal end, a distal end, and a fixation element on the distal end of the anchor wire, the anchor wire flexible and moveable within the lumen of the inner guide catheter and extendable from the opening of the inner guide catheter, the fixation element configured to penetrate tissue of the target site to anchor the anchor wire to the tissue of the target site, wherein the electrode of the inner guide catheter and the fixation element of the anchor wire are electrically connected to a circuit configured to sense a biomarker signal from the bundle of His with the electrode and the fixation element as a bipolar sensing pair.
