What you could know
- Samsung filed a U.S. patent for “steady atrial fibrillation detection through PPG to ECG sign translation” on April 18.
- The patent describes a generative AI mannequin that interprets coronary heart price knowledge as ECG waveforms.
- Samsung, Apple, and Fitbit watches have passive irregular coronary heart rhythm notifications that immediate you to take lively ECGs.
Many smartwatches carry out atrial fibrillation (AFib) spot checks utilizing an ECG sensor, however steady AFib knowledge is not possible with no medical monitor. Final month, Samsung patented a plan to vary that for future wearables just like the Galaxy Watch 7 by using a generative AI mannequin.
First noticed by Wareable, the U.S. patent “System and technique for steady atrial fibrillation detection through PPG to ECG sign translation” would “translate PPG indicators to corresponding ECG waveforms.”
Samsung acquired FDA approval for passive detection of irregular coronary heart rhythm utilizing Galaxy Watches final 12 months, and Fitbit, Apple, and Withings do the identical. However this technique can solely guess at an issue and immediate you to take an lively ECG studying to verify.
Samsung’s patented PPG-to-ECG technique would (hypothetically) provide you with extra definitive knowledge always, making it extra prone to catch the lead-up to critical coronary heart situations like arrhythmia and coronary heart failure.
The patent explains that “standard fashions” can solely depend on “long-term relationships” between PPG coronary heart rhythm knowledge and certain ECG outcomes. With its GenAI fashions, Samsung claims, it’s going to create a “first-order Markov relationship” between them for higher accuracy.
Samsung’s patent acknowledged that by utilizing generative AI, “faux data could also be launched, which impacts an AFib detection outcome.” It plans to unravel this by “incorporating prior information when it comes to probabilistic graphical fashions” in order that it’s “strong to noise,” aka irrelevant or deceptive data.
Samsung’s generative AI plan might make your coronary heart well being knowledge accessible to Google because it usually depends on the Gemini AI; we’ll have to verify when it arrives whether or not this is a matter from a privateness standpoint.

Samsung even describes a “fusion mechanism” between precise ECG readings and GenAI-made ECG waveforms to translate future PPG knowledge into actionable ECGs higher.
Past that, Samsung’s patent is much too technical for a layman to parse fairly, with in-depth equations (see the charts above) displaying the correlation between PPG and ECG knowledge.
What issues to Galaxy Watch homeowners is that this Galaxy AI characteristic will most likely come to the Galaxy Watch 7 and different future wearables, making it the Android smartwatch to beat for anybody involved about their coronary heart well being.
Apple acquired FDA approval to name Apple Watches a “Medical Machine Growth Device” for AFib detection final week (through 9to5Apple), so this patent might assist Samsung even within the enjoying discipline as soon as it is carried out and examined for accuracy.
We’ll see if the upcoming Galaxy Ring — which can have a PPG of its personal — might reap the benefits of this characteristic. Past that, we’re curious to see if Samsung has different GenAI methods to enhance the well being knowledge from its Galaxy Watches.
