Yesterday, March 16, Apple and Stanford Medicine announced the end of Apple Heart Study, which started in December of 2017. 419 093 Apple Watch users participated in the research, making it the largest of its kind. According to Apple, the goal of Apple Heart Study was to diagnose arrhythmia with the help of a smart watch.

As soon as it was disclosed that a participant had an arrhythmia, he received a telemedicine consultation from a doctor, a special patch for ECG reading and special attention in the study of their indicators.

According to the researchers, Apple Heart Study revealed arrhythmia in 0.5% of participants. One - time cardiac arrhythmias, which do not mean the presence of the disease, were found in a much larger number of Apple Watch owners. However, Apple has created an intelligent notification system that informs researchers only about systematic and noticeable problems, thus doesn't create additional work for doctors.

“We are proud to work with Stanford Medicine as they conduct this important research and look forward to learning more about the impact of Apple Watch alongside the medical community. We hope consumers will continue to gain useful and actionable information about their heart health through Apple Watch,” said Jeff Williams, Apple CEO.
