What does the prefix tachy- mean?

Explanation:
Tachy- communicates speed. It describes something occurring quickly, such as a fast heart rate (tachycardia) or rapid breathing (tachypnea). Knowing the opposite helps reinforce the idea: brady- means slow, so bradycardia or bradypnea. Other prefixes deal with position or relation (for example, supra- or hyper- can mean above or more than, and inter- means between), not speed. So tachy- specifically means fast or rapid.
