The heart rate is defined as the number of times the heart has beaten in a minute or over a specific time period due to the circulation of the blood throughout the body. It varies based on the activity of an individual.
Alexandra has a moderate heart rate as she is able to talk but cannot keep the pace of singing along. It is not low, vigorous, or dangerous as she is able to talk with her friends. She is unable to maintain the pace of singing but does not heart rate in any danger zone.
