Heart rate sometimes between 103 and 105. Is that normal?

Heart rate between 103 and 105 beats per minute is sometimes abnormal.

Heart rate refers to the number of beats per minute of the heart, which may vary depending on individual differences, physiological conditions and environmental factors. Under normal quiet conditions, the heart rate of adults is usually considered to be a normal heart rate range between 60 and 100 beats per minute. The examiner's heart rate between 103 and 105 beats per minute is abnormal, which may be caused by factors such as sleep disorder and anemia.

Before measuring heart rate, try to keep the body relaxed and still. Activity or stress may cause the heart rate to increase, thus affecting accuracy.
