Apple Watch was able to detect irregular heart rate rates that could signal the need for further monitoring for a serious heart rhythm problem, according to data from a large study funded by Apple which shows a potential future role for portable consumer technology in healthcare.
Researchers hope that the technique can help in early detection of atrial fibrillation, the most common form of irregular heartbeat. Patients with untreated AF are five times more likely to stroke.
Results of the largest AF screening and discovery study, involving over 400,000 Apple Watch users who were invited to attend, presented on Saturday at the American College of Cardiology meeting in New Orleans.
Scientists at Stanford Medical School revealed that the 400,000 participants, 0.5 percent or about 2,000 subjects, received irregular pulse messages. These individuals were sent an ECG (electrocardiography) patch to carry for subsequent detection of atrial fibrillation episodes.
One third of those whose bells discovered an irregular pulse were confirmed to have atrial fibrillation using ECG technique, researchers said.
Thank you to the team at @ StanfordMed were the researchers and participants who made this groundbreaking study possible. https://t.co/RSLOMTU1uN

The study also found that 57 percent of the participants who received an alert on their watch sought medical attention.
For Apple, the data provides firepower when it presses into health care. The new series 4 Watch, which became available only after the study began to be used, has the ability to take an electrocardiogram to detect cardiac problems and required clearance from the US Food and Drug Administration.
Dr. Deepak Bhatt, a cardiologist from Brigham and Women & # 39; s Hospital in Boston who was not involved in the trial, called it an important study, as the use of this type of portable technology will only be widespread.
"The study is an important first step to figuring out how we can use these techniques in a way that is evidence-based," he says.
Researchers urged doctors to use caution when using data from consumer devices in treating patients. also sees great future potential for this type of technology. "" Atrial fibrillation is just the beginning, as this study opens the door to further investigate useful techniques and how they can be used to prevent disease before it strikes, "said Lloyd Minor, dean of Stanford School of Medicine
