HR stands for which term?

• A. Heart rate
• B. Heart rhythm
• C. Hemorrhagic rate
• D. Hypovolemia rate

Answer: (A)

HR stands for heart rate, the frequency of heartbeats per minute. This is a key vital sign used to assess cardiac function. You typically measure it by counting beats over a set time (often 15 seconds and multiply by four, or a full minute if the rhythm is irregular). Heart rate is different from heart rhythm, which describes the pattern of beats (regular vs irregular) rather than how often they occur. The other terms listed aren’t standard meanings of HR; they describe rhythm or concepts not denoted by the abbreviation. In practice, normal ranges vary by species and size (for example, dogs often 60–160 bpm, cats 140–220 bpm), and noticeable changes can indicate stress, pain, or disease.
