ABSTRACT:
A cardiac pacemaker electrode including an electrode tip having an external surface with a concave region formed therein to increase the pacing impedance thereof. Further, the external surface of the electrode tip is roughened, for example by abrading with a jet of glass beads projected under pressure, to increase the microsurface area of the electrode tip and to reduce the sensing impedance thereof.
