Samsung Galaxy Watch could get LVSD detection through ECG readings

Samsung is rolling out a new health feature for Galaxy Watch users that can detect signs of Left Ventricular Systolic Dysfunction (LVSD), a form of heart failure. It uses ECG data from the watch, analysed by an AI algorithm, to spot early warning signs in people who may not show any symptoms. For now, the feature is limited to South Korea, though broader availability may follow.

A new use for ECG readings

LSVD is a condition where the heart’s left ventricle can’t pump blood efficiently, often without any noticeable symptoms in the early stages. The key is early detection, and Samsung is trying to deliver that through its watches.

To make this work, the company is tapping into an algorithm developed by Medical AI. It analyses ECG data from Galaxy Watch devices to spot signs of LVSD. Apparently, this algorithm has already been validated against the gold standard of 12-lead ECGs, and the results were promising.

For now, the feature is delivered through the AiTiA LVSD-1L app, also made by Medical AI. It’s been approved by South Korea’s Ministry of Food and Drug Safety, so it’s cleared for use in that market. There’s no timeline yet for when it might expand internationally. The U.S. launch in particular hinges on getting FDA approval, which has not been secured.

Potential for wider rollout

There is the possibility that this could eventually become part of the broader Samsung Health Monitor app. That would make it more seamless for users already tracking blood pressure or ECG data with their watches. But at this stage, there’s no confirmation on whether this feature will be available on all Galaxy Watches that support ECG. Compatibility may depend on hardware or software versions.

Also unclear is whether this new functionality will be limited to Galaxy phones. That’s been a frustrating limitation in the past. Many people use Galaxy Watches paired with non-Samsung phones, and restricting this kind of health feature to Samsung-only devices would be a missed opportunity.

The hope is that the new feature can also drive lifestyle change. Catching potential heart failure risks early might nudge people toward improving their sleep, diet, or exercise habits before more serious intervention is needed. This could reduce long-term healthcare costs by helping people avoid expensive treatments down the line.

It’s a good example of how wearables are slowly creeping into clinical territory. More than just fitness trackers, these devices are starting to offer tools that could complement traditional health screenings. That said, they’re still not replacements for actual medical diagnostics, and users should treat these results as prompts to seek professional advice, not as final verdicts.
