What does the prefix "Brady-" signify?

The prefix "Brady-" originates from the Greek word "bradus," which means slow. In medical terminology, it is commonly used to describe conditions related to a slower than normal rate, particularly in terms of heart rate, often referred to as bradycardia. This significance is important in various clinical contexts, such as when assessing a patient's physiological state. The other options do not align with the meaning of "Brady-." For instance, “fast” would imply a condition characterized by an elevated rate, while “above normal” and “below normal” describe a general state without the specific connotation of slowness conveyed by "Brady-."
