Abstract
A pacemaker which generates a triphasic stimulus; the first and third phases are positive pulses, and the second is the negative stimulus. After-potentials are so low that reliable sensing of evoked signals are possible. The rapidity of the charge balancing is not affected by the stimulus amplitude because the relative amplitudes of the three phases are maintained independent of the stimulus amplitude.
