Meanwhile, heart rate monitors used in medical settings connect a set of electrodes to an electrocardiogram (ECG) machine via wires. The sensors usually sit on the inside of the wrist, which is where many medical professionals recommend measuring pulse rate manually, or on the chest just below the heart. Heart rate monitors designed for personal use typically feature such optical sensors that can measure heart rate through the skin’s surface. The ways in which light scatters as blood dynamics change (such as with a variable heart rate) is thought to be predictable and can therefore be captured by an algorithm that translates the information into a real-time heart rate reading.

Essentially, PPG involves shining light into the skin and subsequently measuring the amount of light that’s scattered by the body’s blood flow. Optical heart rate monitors use photoplethysmography (PPG) technology to measure heart rate.
