词源

From Late Middle English pulse, Middle English pous, pouse (“regular beat of arteries, pulse; heartbeat; place on the body where a pulse is detectable; beat (of a musical instrument); energy, vitality”) [and other forms], from Anglo-Norman puls, pous, pus, and Middle French pouls, poulz, pous [and other forms], Old French pous, pulz (“regular beat of arteries; place on the body where a pulse is detectable”) (modern French pouls), and from their etymon Latin pulsus (“beat, impulse, pulse, stroke; regular beat of arteries or the heart”), from pellō (“to drive, impel, propel, push; to banish, eject, expel; to set in motion; to strike”) (ultimately from Proto-Indo-European *pel- (“to beat, strike; to drive; to push, thrust”)) + -sus (a variant of -tus (suffix forming action nouns from verbs)).
