The Apple Watch can soon help cardiologists find out about heart conditions

A smartwatch can become a second cardiologist soon. After a series of studies, scientists from the University of California, San Francisco, discovered that if an Apple Watch combined with an app from Cardiogram Inc., it can detect whether users have heart disease or not as well as follow up its user’s diet and sleep mode.

The studies use Step rate counter and Heart rate sensors, which are integrated into Apple Watch to monitor the data about heart disease known as atrial fibrillation. This disease is a type of abnormal heart rhythm condition, which can lead to blood clots and strokes

The data obtained from 6,680 Apple Watch’s owners, including 50 people who suffer from atrial fibrillation, have been accessed through an app from Cardiogram inc. A founding research company sponsors this work. The final information then under further analyzed by the Machine Learning system and eventually come up with some interesting conclusions.

Firstly, the Heart Rate of the Apple Watch works with 97% accuracy when sedentary uses.

In the case of people who are active or only do regular daily tasks, the detection rate has decreased to 72%. This significant difference is due to more physical activity, the heart rate increases, which causes the Apple Watch to monitor the heart rate less throughout the day.

Atrial fibrillation affects more than 2,700,000 Americans and 34,000,000 people worldwide. Some may not know they are suffering from atrial fibrillation because the symptoms which including chest pain, irregular heart rate, fatigue while exercising and breathing fast, can’t be recognized by patients. It is very dangerous if these symptoms are not treated, atrial fibrillation can lead to severe complications.

This research is part of the eHealth Heart project. It started again in 2013 and aims to prevent heart diseases by using the power of mobile technology. So far, the project has more than 160 000 participants but expected to reach 1 million by the end of this year.
