The pacing lead assembly (10) comprises a flexible pacing lead (12) having, at the proximal end thereof, terminals (14, 16) for connecting the lead (12) to a pulse generator, and having a flexible bent or curved configuration (23) in an outer end portion (22) thereof with an electrode assembly (24) including an electrode (28) at the distal end (25) of the pacing lead (12). A positionable, locating, orienting and stabilizing device (34) has a passageway (38) therethrough and is received over the lead (12) such that the device (34) can be rotated on the pacing lead (12). A cooperating locking hub (36) is fixed on the lead (12) and adapted to mate and lock with the device (34) in a predetermined position of the device (34) whereby the device (34), when locked in place in the predetermined position, has a predetermined orientation relative to the bent or curved configuration (23) in the outer end portion (22 ) of the pacing lead (12) and whereby the device (34) in its unlocked position can be rotated to an unobtrusive position relative to the outer end portion (22) of the pacing lead (12).
