AB  - The accuracy and tracking ability of nine commercially available heart rate monitors were assessed. The heart rate of 16 young healthy men was continuously monitored by a single-lead electrocardiograph while they exercised on a stationary bicycle ergometer. Readings were obtained from the devices during exercise. The devices that measured the cardiac electrical potential with a three-electrode system or that incorporated a light transmission device attached to the earlobe were the most accurate and provided suitable monitoring of the heart rate during exercise.
