pulse gen·er·a·tor

a device that produces an electrical discharge with a regular or rhythmic waveform in which the electromotive force varies in a specific pattern in relation to time; for example, in an electronic pacemaker, it produces an electric discharge at regular intervals, and these intervals may be modified by a sensory circuit that can reset the time-base for subsequent discharge on the basis of other electrical activity, such as that produced by spontaneous cardiac beating.
