The skin color on a person's face may reflect whether the person is suffering from a form of heart rhythm disorder called atrial fibrillation.

Atrial fibrillation is an electrical disturbance in the atria that causes muscle twitching into irregular and irregular vibrations, a disease that can be dangerous but treatable.

With the help of cameras and computer software algorithms, experts from the University of Rochester (USA) have proven that by observing small changes in skin color , we can detect love. Uneven blood circulation due to atrial fibrillation.

The technology uses the algorithm developed by Xerox, scans the face and has since found changes in skin color that the naked eye cannot capture, according to the Heart Rhythm report.

The sensors in digital cameras are designed to recognize 3 colors: red, green, blue.

Hemoglobin absorbs a lot of green light, and this small change can be exposed by camera sensors.

The study showed that this method has a error rate of 20%, compared with 17-29% if ECG measurement is used.
