These light-sensitive photodiodes and green LEDs are used to measure arterial blood flow. These optical sensors in the Apple Smartwatch can detect heart rates between 30 and 210 times per minute.

Although it is not a replacement for professional medical care, the heart rate app can provide helpful information about your cardiovascular system.
