What is the normal circulatory rate for an adult?

The normal circulatory rate, or heart rate, for an adult is generally accepted to be between 60 and 100 beats per minute. This range is considered healthy for most adults at rest, as it reflects the heart's ability to supply blood effectively throughout the body while meeting metabolic demands.

A heart rate below this range, such as 40-60 beats per minute, may indicate bradycardia, which can be a sign of an underlying health issue if symptomatic. Conversely, a heart rate above 100 beats per minute can indicate tachycardia, which may result from various factors including stress, exercise, or medical conditions. The values that suggest 80-140 beats per minute and 150-180 beats per minute fall outside the typical resting heart rate range for adults, making them less applicable to this question. Understanding this range is crucial for recognizing normal versus abnormal heart rates in different contexts, including emergency situations.
