A catheter used to deliver a medical electrical lead to a right atrium of a heart in close proximity to a His bundle. The catheter is adapted such that the distal tip confronts the His bundle generally perpendicularly. The catheter includes a proximal portion and a generally hook-shaped distal portion. The distal portion may include curves that direct the distal tip at an angle of over 180 degrees from the direction of the proximal portion.
