What is the typical heart rate considered normal for an adult at rest?

The typical heart rate considered normal for an adult at rest is between 60 and 100 beats per minute. This range is established based on extensive research and is widely accepted in both clinical practice and guidelines. At rest, a heart rate within this range indicates efficient cardiac function and a well-regulated autonomic nervous system, which helps maintain blood circulation and oxygen delivery to tissues.

A heart rate lower than 60 beats per minute may be seen in well-trained athletes due to increased heart efficiency; however, it could also indicate bradycardia, a condition that might require further evaluation depending on associated symptoms. Conversely, a heart rate above 100 beats per minute is classified as tachycardia, which can suggest underlying health issues such as stress, anxiety, or cardiovascular conditions.

Understanding the normal heart rate range is essential for healthcare professionals when assessing cardiovascular health and determining the need for further investigation or intervention.
