What is the average heart rate for adults (older than 15 years)?

The average heart rate for adults, specifically those older than 15 years, typically ranges from 60 to 100 beats per minute. This range is considered normal according to many medical guidelines and reflects the resting heart rate in a healthy adult. Factors such as age, fitness level, and overall health can influence an individual's heart rate; however, the 60-100 bpm range serves as a standard baseline for adults in general.

Heart rates outside this range can indicate various health issues. A resting heart rate significantly lower than 60 beats per minute (bradycardia) or higher than 100 beats per minute (tachycardia) may require further assessment and monitoring depending on the individual’s health history and other symptoms.

In contrast, while the other ranges mentioned may apply to certain populations, they do not accurately represent the established average heart rate for adults. For instance, the ranges of 50-70, 70-110, and 80-120 beats per minute overlap populations such as athletes or very young children, which is why they do not fit the general criteria for adults.
