The Apple Watch has the potential to become a lifeguard. Your built-in heart rate monitor is extremely accurate and can detect cardiac arrhythmia by up to 97 percent. This resulted in a new study.
The study of the University of California and the Cardiogram App involved 6158 Apple Watch users, who monitored their pulse with the health application. Most users had a normal heart attack and a normal ECG, but 200 subjects started with the diagnosis paroxysmal prescreening (a common form of cardiac arrhythmia).
Based on the data collected by Apple Watch, 139 million heart rate measurements and 6338 mobile ECGs, scientists trained a neural network. This should identify cardiac arrhythmia.
With success as shown in the following test: 51 people who were registered for a cardioversion, a special defibrillation form that restores the normal heart rhythm, carried an Apple Watch 20 minutes before and 20 minutes after the procedure. The AI should then evaluate the data. The results of the experiment were convincing: with an accuracy of about 97 percent, the AI-based solution detected a pre-flash.
These results show that wearables, such as smartwatches, are not only a new way to monitor medical therapies for cardiac arrhythmias but can also point to health issues. Even though mobile controls will never replace conventional examination methods, they have the potential to draw people’s attention to the fact that they may suffer from a pre-emptying.
The study started in 2016 and continues to grow. Building on these results, the researchers now want to determine whether Apple Watch can also identify an impending stroke. According to Cardiogram co-founder and scientist Brandon Ballinger, a quarter of all strokes are triggered by cardiac arrhythmias.
