What is the normal range for a healthy adult's resting heart rate?

The normal range for a healthy adult's resting heart rate is between 60 and 100 beats per minute. This range is established based on the physiological responses of the body at rest, indicating an efficient cardiovascular system. A resting heart rate within this range typically reflects good cardiovascular health and adequate oxygen supply to the body's tissues.

Heart rates lower than this range, such as the 40-60 beats per minute interval, could indicate bradycardia, which may be normal in well-trained athletes but could signal an issue in non-athletes. Similarly, a heart rate that exceeds 100 beats per minute at rest may suggest tachycardia, potentially indicating stress, anxiety, or underlying health concerns that warrant further investigation.

Understanding this normal range is crucial for assessing a patient's vital signs and determining their overall health status, making the knowledge of 60-100 beats per minute essential for emergency care providers.
