How Does a Heart Monitor Work?
A heart monitor, also known as a “heart rate monitor,” lets you know what your exercise intensity is while you work out. This can be a valuable tool that can keep you working at a desired level. A heart rate monitor comes equipped with a chest strap and a watch that you wear on your wrist. Although there are a lot of different companies that produce these, they all function the same basic way. The chest strap has electrodes with a built-in transmitter. These electrodes get moistened with water and the strap is snugly placed on your chest across the breast bone. The electrodes need good contact with your skin right next to your heart.
