Apple and Stanford Universityinvestigated the accuracy of the work of "smart" watches Apple Watch in terms of tracking violations and anomalies of the user's heartbeat and recommendations of the appeal to the doctors. The results of the analysis recently published on the university website.
400,000 Apple owners participated in the projectWatch. This is the most large-scale scientific project that tracks heartbeat. As a result, it turned out that only 2,000 participants (5% of the total) received notifications of heart failure from these hours.
This was followed by an ECG study,which showed that 84% of those who received notifications actually had atrial fibrillation. We are talking about atrial fibrillation, one of the most common types of atrial dysfunction.
Scientists believe that current technologyApple Watch's heart rate monitor is far from ideal. It still needs to be improved. One of the leaders of the research, Professor Mintu Turakhia, noted that even when the watch did not reveal any irregularities in the heart’s work among users, this did not mean their absence.
Other Project Manager Cardiologist KennethMahaffi, who works at the Stanford School of Medicine, said that it is worthwhile to work on understanding what exactly this technology should be implemented in modern medical practice.
It is worth noting that for the first time Apple smart watchesWatch was first introduced 4.5 years ago. The fourth generation of the gadget was equipped with ECG technology for 30 seconds. As experts have established, the watch can also with an accuracy of 85% determine whether the user has diabetes.
