Abstract
A myocardial pacing lead includes two sets of at least two tines placed to oppose each other. The lead is pressed against the epicardium and is rotated until a rough porous tip abrades the epicardium and allows the tip and the first row of tines to penetrate the myocardium. Excessive penetration and lead migration is prevented by the second row of tines which is mounted backward and just proximal from the first row of tines. The first row of tines anchor on the inside surface of the epicardium which prevents dislodgment. Dacron pads on the second row of tines assures chronic fixation by adhering to the outer surface of the patient's epicardium.
