Which prefix meaning slow is used in terms like bradycardia?

The main idea is that medical prefixes convey speed, with brady- meaning slow. In bradycardia, the prefix brady- indicates a slow heart rate, since cardia refers to the heart. Bradycardia describes a heart rate that is slower than normal (below about 60 beats per minute). The other prefixes don’t mean slow: tachy- means fast (as in tachycardia), hyper- means above normal or excessive, and apo- means away from or detached, which aren’t about speed. This same slow-prefix shows up in terms like bradykinesia, where movement is slower, reinforcing how brady- consistently signals slowness.
