Apple has launched the Heart Study app that will collect data on irregular heart rhythms and notify users who may be experiencing atrial fibrillation (AFib). The calculation is done via the heart rate and rhythm, the app detects the amount of blood flowing through the wrist. Apple Watch’s sensor uses green LED lights flashing hundreds of times per second and light-sensitive photodiodes to detect the same.
According to Apple, the optical design of the sensor gathers signals from four distinct points on the wrist. In case an irregular heart rhythm is identified, participants will receive a notification of their Apple Watch and iPhone.
Jeff Williams, Apple’s COO, writes,
“Every week we receive incredible customer letters about how Apple Watch has affected their lives, including learning that they have AFib. These stories inspire us and we're determined to do more to help people understand their health. Working alongside the medical community, not only can we inform people of certain health conditions, we also hope to advance discoveries in heart science.”
Apple has partnered with Stanford Medicine to perform the research.
Lloyd Minor, Dean of Stanford University School of Medicine,
“Through the Apple Heart Study, Stanford Medicine faculty will explore how technology like Apple Watch’s heart rate sensor can help usher in a new era of proactive health care central to our Precision Health approach. We’re excited to work with Apple on this breakthrough heart study.
For now, the Apple Heart Study app is available in the US App Store for the customers who are 22 years or older and have an Apple Watch Series 1 or later.
