Answer: (B)

The prefix that indicates a fast heart rate is "tachy-." This term is commonly used in medical terminology to describe conditions where there is an increased heart rate, specifically one that exceeds the normal range. "Tachy-" is derived from the Greek word "tachus," meaning swift or fast. In the medical context, it is often seen in terms such as "tachycardia," which refers to a heart rate that is faster than normal, typically over 100 beats per minute in adults at rest. Recognizing this prefix helps healthcare professionals identify and communicate issues related to heart rhythms effectively. The other prefixes provide context for different conditions: "brady-" indicates a slow heart rate, "hypo-" refers to lower than normal levels or rates, and "normo-" refers to normal levels or rates. Understanding these prefixes is essential for precise medical terminology.
