Speaking of Apple Watch and heart problems, here’s the opposite end of the spectrum: the developers of Cardiogram are working with researchers of the UCSF Health eHeart Study to understand if heart rate data captured by smartwatches can generate insights to prevent strokes.

Heart researchers from the University of California, San Francisco as well as developers behind the heart rate-tracking app Cardiogram are teaming up to investigate if the tech built into smartwatches could be used to identify those at risk for a stroke or heart failure.

The research team will be honing in on one of the most commonly undiagnosed irregular heart conditions: atrial fibrillation, an irregular and often rapid heart rate also known as a type of arrhythmia.

Working within an observational study dubbed mRhythm, which kicked off on Wednesday, researchers will track data from participants using both the Apple Watch and Android Wear-based devices while looking for signs of irregular heart rates. These kinds of watches don’t have advanced electrocardiogram (EKG) machines inside. But they do include cheaper technology, such as LED lights, which can be used to measure blood flow in the wrist.

Like Apple’s ResearchKit, if these crowdsourced studies can lead to early diagnoses and better prevention, the impact of wearable devices on our lifestyle will be meaningful.
