A pulse in electrotherapy is defined as which?

Explanation:
In electrotherapy, a pulse is a finite burst of current that has a defined shape made up of one or more phases. Each phase is a portion of the current with a specific polarity and duration, and when you put these phases together you get the overall pulse waveform. Monophasic pulses have a single phase, while biphasic pulses have two phases with opposite polarity, and more complex pulses can have multiple phases. This structure—phases forming the pulse—distinguishes a true pulse from a simple instantaneous spike, a continuous unbroken wave, or a current with no on/off periods.
