Apple Watch has been able to detect irregular heartbeats to allow early intervention to monitor a serious heart condition, according to data from a large study funded by Apple, pointing to a potential future role of smart devices in the field of cancer care. health.
The researchers hope this technology will help detect early atrial fibrillation, the most common form of irregular heartbeat. Even patients with untreated atrial fibrillation are more likely to have a stroke five times.
The results of the largest Atrial Fibrillation Detection and Surveillance study, which included more than 400,000 Apple Watch users invited to participate, were held Saturday at the American College of Cardiology meeting. in New Orleans.
Of the 400,000 participants, 0.5%, or about 2,000 people, received notifications from the Apple clock with irregular impulses. These people were then sent under an ECG-ECG patch to monitor the subsequent detection of AF.
One-third of those with irregular pulse times confirmed their atrial fibrillation using an electrocardiogram, researchers said. The data also showed that about 84% of irregular pulse notifications were later confirmed as atrial fibrillation. The study also revealed that 57% of participants who had received an alert under their supervision had sought medical attention.

"The doctor can use the information from the study, combine and evaluate them … then guide clinical decisions about the use of the alarm," said Dr. Marco Pérez, researcher Principal at the Stanford School of Medicine.
As for Apple, the results of this study represent a powerful boost in its healthcare strategy. Even the fourth generation of its smartwatch, which went on sale after the start of the study and has not been used, has the ability to measure heart rate to detect heart problems and expects a license of the US Food and Drug Administration.
Dr. Deepak Bhatt, a cardiologist at Brigham and Women's Boston Hospital, who did not participate in the trial, said the study was important because the use of this type of portable technology would become widespread.
The researchers urged doctors to be cautious when they use data from mainstream devices to treat their patients. But they also see great potential for this type of technology. "Atrial fibrillation is only the beginning," said Lloyd Minor, dean of the Stanford School of Medicine. "This study opens the door to new research on wearable techniques and how to use them to prevent disease before it happens."
