Apple launched a large-scale heart rate study in collaboration with Stanford Medicine in November 2017. The study (called Apple Heart Study) was conducted to improve technology that identifies irregular heart rhythms. Early diagnosis and treatment can prevent life-threatening heart complications, including strokes.
The study was carried out in the form of an app, open to all Apple Watch owners in the United States, 22 years and older, with a Series 1 or above. It measured heart rhythm and heart rate using the Apple Watch’s LED sensor and light-sensitive photodiodes to detect the amount of blood flowing through a person’s wrist. It was able to isolate heart rhythms from other noise in order to detect irregular heartbeats, with the use of AI technology.
The study was closed to new participants at the start of last month, with Apple also informing some users who signed up that their contribution is complete. The end is in sight as the study is expected to come to a conclusion in January 2019.
It is still unclear as to what Apple and Stanford Medicine will do with the results from their study, and if it will be utilized to equip future Apple Watch devices to bring the results into effect.
