The prefix 'Brady-' refers to which of the following conditions?

The prefix 'Brady-' is derived from the Greek word "bradys," which means slow. It is commonly used in medical terminology to describe conditions characterized by a slower than normal rate, such as bradycardia, which refers to a slower heart rate. Understanding medical prefixes is important as they provide insight into the nature of various conditions and their definitions, enhancing knowledge of anatomy and physiology. The other options relate to different prefixes or concepts; for example, 'Tachy-' refers to fast, 'Bi-' generally means two, and 'Anti-' means against, which clearly do not relate to the meaning of 'Brady-'.
