Heart Rate
Heart rate is the number of times the heart beats per unit of time, usually measured in beats per minute, serving as a vital sign of cardiovascular function and overall health. It fluctuates with factors like exercise, emotions, and rest, making it a key metric in fitness apps and medical monitoring to detect issues early and optimize performance.
