Left heart failure can be detected by the Apple Watch ECG

The Apple Watch’s electrocardiogram can alert a patient with left ventricular failure (or heart pump failure) using an algorithm developed by the Mayo Clinic. And this despite the unique lead of the watch’s ECG sensor.

There’s no need to pass a 12-lead full electrocardiogram in the clinic, which is much more complicated to perform than on the Apple Watch—just place your finger on the digital crown for 30 seconds and pim.

Basically, the ECG of the Apple Watch can detect atrial fibrillation, while the heart rate monitor continuously measures the heart rate. In the event of an arrhythmia (irregular beat, too fast or too slow), the Apple Watch sends a notification to the wearer. The manufacturer can add this left ventricular failure alarm to its arsenal if it happens to integrate the algorithm developed by the famous American clinical network.

This insufficiency affects 2 to 3% of the world’s population and up to 9% of those over 60 years of age. It’s starting to bother a lot of people, especially since abortion doesn’t necessarily come with symptoms (however, the condition can be accompanied by difficulty breathing, swelling of the legs, or even an accelerated heartbeat).

Once the doctor knows that a patient has this disease, he can act accordingly: there are treatments. What I need to know… A diagnosis of left ventricular failure is made with an echocardiogram, a scanner, or an MRI. This is where the Apple Watch comes into play, on which it is very easy to take an EKG. To design this algorithm, the researchers modified the algorithm used with a twelve-lead electrocardiograph.

In order to adapt this technique to a single-lead ECG, artificial intelligence had to be used. To verify and refine the results, a study was organized with 2,454 participants from 11 countries, owners of iPhones, the Mayo Clinic app and an Apple Watch Series 4 or later, who sent more than 125,000 electrocardiograms over a six-month period .

According to preliminary data, the algorithm performs as well or slightly better than a traditional test. ” Artificial intelligence analysis of a watch’s ECG is a powerful test to identify left ventricular failure says dr Itzhak Zachi Attia, AI Manager in the Department of Cardiovascular Medicine at the Mayo Clinic.

This test definitely shows that the Apple Watch’s EKG, although limited with its unique lead, can provide useful medical information. Enough to support the watch’s “clinical use on the wrist”.
