This weekend, Stanford Medicine researchers presented the long-awaited results of the Apple Heart Study, which explored the performance of the Apple Watch’s heart rate sensor and an accompanying algorithm in detecting potential arrhythmias. Funded by Apple and launched back in 2017, the research project enrolled 419,297 Apple Watch and iPhone owners. Among these users, 2,161 (roughly 0.5 percent...

According to a new study published this morning in Nature, an algorithm trained via a deep neural network has been able to perform on par with board-certified cardiologists at the annotation of 12 different types of heart rhythms. Researchers from Stanford University and iRhythm collaborated for the study, which detailed an algorithm trained on 91,232 30-second single-lead ECG readings from 53,...

As predicted, the Apple Watch's version 5.1.2 update went live today, giving anyone in the United States with an Apple Watch Series 4 the ability to take an ECG reading on the wrist. Alongside the active ECG, the Watch's passive irregular rhythm detection feature launched today as well. "We are confident in the ability of these features to help users have more informed conversations with their...

Last week FibriCheck announced that it received FDA 510(k) clearance for its app, which uses a smartphone’s camera and artificial intelligence to monitor for heart rhythm disorders. With this, the Belgian company expects to bring its product to the US market sometime in 2019. To identify atrial fibrillation, FibriCheck monitors the user's heart rhythm via photoplethysmography. From there, an...

A take-home wearable ECG could be key in detecting undiagnosed atrial fibrillation, according to a new study published in JAMA this morning. Researchers from The Scripps Research Institute used the iRhythm Zio patch, an ECG screening wearable, to monitor patients with a risk for the condition.  Researchers discovered that patients who immediately began monitoring were significantly more likely to...
