HR stands for

HR stands for

• A. Heart rhythm
• B. Hemorrhage rate
• C. Heart rate
• D. Health rate

Answer: (C)

HR is Heart Rate—the number of times the heart beats per minute. This vital sign helps gauge how the cardiovascular system is functioning and how it responds to activity, stress, or illness. It’s different from heart rhythm, which describes the pattern of beats (regular or irregular) rather than how many beats occur in a minute. A typical resting range for adults is about 60–100 bpm, though well-trained athletes may have lower resting rates. You can measure HR by feeling a pulse, listening with a stethoscope, or using a monitor or ECG. The other options refer to different concepts (heart rhythm, hemorrhage rate, health rate) and aren’t what HR stands for.
