'Stimulant' is a broad category (e.g., caffeine, amphetamines) that affects the entire central nervous system. 'Cardioaccelerator' is a specific functional term describing only the effect of increasing heart rate, which can be caused by a specific nerve, a reflex, or one specific action of a stimulant drug.
