What is the normal range for an adult human heart rate in beats per minute?

The normal range for an adult human heart rate is 60 to 100 beats per minute, which is why this option is the correct choice. This range is considered the standard for resting heart rates in healthy adults. A heart rate below this range, typically falling between 40 to 60 beats per minute, can indicate bradycardia, which might be a concern in certain situations. Conversely, a heart rate above 100 beats per minute is classified as tachycardia, which may indicate an overactive state or potential health issues such as anxiety, dehydration, or heart-related problems. Understanding the normal range helps healthcare professionals assess a patient's cardiovascular health.
