The electrode assembly (10) is adapted to be mounted at the distal end of a pacing lead (19) and comprises a mushroom shaped tip electrode (12, 90) having a reduced in diameter terminal pin (22, 42, 62, 92) extending rearwardly therefrom. A sleeve (34) of insulating material is positioned about said terminal pin (22, 42, 62, 92) and a coiled single or multiple wire conductor bared end portion (18, 44, 64, 96) of the pacing lead (19) is received on the terminal pin (22, 42, 62, 92) within the sleeve (34). The pin (22, 42, 62, 92) has a spiral, thread-like formation (48; 98,100) or ramp formation (66) thereon onto which the bared wire conductor end portion (18, 44, 64, 96) is threaded to form a secure and good mechanical and electrical connection (35, 60, 80, 110) between the terminal pin (22, 42, 62, 92) and the bared wire conductor end portion (18, 44, 64, 96).
