'pulsation' originates from Latin, specifically the word 'pulsatio,' where 'pulsare' meant 'to beat or strike.'

'pulsatio' transformed into the Old French word 'pulsation,' and eventually became the modern English word 'pulsation' through Middle English.

Initially, it meant 'a beating or striking,' but over time it evolved into its current meaning of 'a rhythmic throbbing or vibrating.'
