In a joint study published today, Cardiogram and researchers at the University of California, San Francisco (UCSF) relied on the Apple Watch -- and Cardiogram's algorithm -- to gather heart rate and electrocardiogram data from 6,158 individuals. Their goal? To determine if the Apple Watch's sensors can differentiate between a normal heart rhythm and atrial fibrillation (AF). Apparently, it can; the study identified AF with 97 percent accuracy.

An Apple representative did not have anything specific to share about Cardiogram, but directed C/NET's Megan Wollerton to a Johns Hopkins University study, which detailed findings about detecting potential seizures with the Apple Watch. For more on this, check out the full report here.
