词源

Inherited from Middle English pulsacioun (“pulsing of the blood, throbbing”), borrowed from Middle French pulsacion (“(of bells) a striking (end of 14th c.); (of a diseased part of the body) a throbbing (1377); pulsation (1575)”), and its source, Latin pulsātiō (“(classical Latin) a beating or striking; (Medieval Latin, medical) rhythmical expansion and contraction (1363 in Chauliac)”). By surface analysis, pulsate + -ion.
