Which part of the term 'bradycardia' indicates slow?

The term "bradycardia" is derived from Greek roots, where "brady-" signifies the concept of slowness. In medical terminology, "brady-" is a prefix used to describe conditions that involve a slower-than-normal rate. Thus, in the context of bradycardia, this prefix indicates a slower heart rate than what is typically considered normal.

The second component, "cardia," refers to the heart, while the suffix "-ia" indicates a condition or state. The combination of these parts creates a term that specifically describes a condition related to a slower heart rate. Understanding these root components is essential for medical terminology, as they help in deciphering the meanings of various terms based on their prefixes and suffixes.
