Among those whose heart rates rose above 85, there were 17.2 deaths per 10,000 people per year. Among the group whose heart rates stayed under 70 throughout the study, there were 8.2 deaths per 10,000 people per year.

The increase in risk was slightly less for those with resting heart rates of 70 to 85 at the study’s start and who had a greater than 85 at the study’s end.Īlthough 90% sounds like a huge and scary increase, let me put it in perspective. They recruited more than 29,000 people without any history or heart disease, high blood pressure, or any other type of cardiovascular disorder, and measured their resting heart rates when they started the study and again 10 years later. This study was published in the Journal of the American Medical Association.Ĭompared to people whose resting heart rates were under 70 beats per minute at the study’s start and its end, those whose resting heart rate rose from under 70 to more than 85 were 90% more likely to have died during the course of the study. Researchers from Norway previously reported the results of a large study looking at changes in resting heart rate over 10 years. Results of observational research studies support a link between health and heart rate. (In his prime, champion cyclist Miguel Indurain had a resting heart rate of just 28 beats per minute.) Stress, medications, and medical conditions also influence your resting heart rate. Regular exercise tends to slow your heart rate down. Many factors influence your resting heart rate. The usual range for resting heart rate is anywhere between 60 and 90 beats per minute. Your resting heart rate, though, tends to be stable from day to day. It depends on whether you are standing up or lying down, moving around or sitting still, stressed or relaxed.

Your heart rate changes from minute to minute. An increase in your resting heart rate over time may be a signal of heart trouble ahead. When you sit quietly, your heart slips into the slower, steady pace known as your resting heart rate.
