A normal resting heart rate for adults ranges from 60 to 100 beats per minute. Generally, a lower heart rate at rest implies more efficient heart function and better cardiovascular fitness. For example, a well-trained athlete might have a normal resting heart rate closer to 40.
For adults, a fast heart rate is generally defined as a heart rate over 100 beats per minute. However, what's considered too fast may also.
Normal heart rate varies from person to person, but a normal range for adults is 60 to 100 beats per minute, according to the Mayo Clinic.

The normal resting heart rate for adults over the age of 10 years, including older adults, is between 60 and 100 beats per minute (bpm).
