amplitude

Cardiac pacing The maximum absolute value attained by an electrical waveform, or any quantity that varies periodically; pacemaker amplitudes express the value of the potential difference in volts or current flow in amperes; pacemaker output pulses have typically averaged 5 volts and 10 milliamps.
