What is considered a normal range for an adult's heart rate?

The normal range for an adult's heart rate is defined as 60 to 100 beats per minute. This figure is based on extensive physiological research indicating that a resting heart rate within this range is typically healthy for most adults.

Heart rate can be influenced by a variety of factors, including age, fitness level, emotions, and overall health. A resting heart rate below 60 beats per minute may be normal for well-trained athletes who have superior cardiovascular efficiency, but in the general population, a rate below 60 could signify bradycardia, which may require further assessment. Conversely, a resting heart rate consistently above 100 beats per minute might indicate tachycardia, prompting a need for medical evaluation, particularly if there are other symptoms present.

The ranges provided in the other options do not align with standard medical guidelines for a normal adult heart rate. By understanding the normal range of 60 to 100 beats per minute, one can better assess cardiovascular health and identify potential issues warranting further investigation or intervention.
