To train the models, Apple broke the recordings into short 5-second clips, moving forward one second at a time. That added up to around 23,000 heart sound snippets, to which Apple then trained a ...

The ring is used to acquire nocturnal heart rate (HR) and HR variability (HRV) parameters ubiquitously. However, these parameters are highly susceptible to motion artifacts and environmental noise.

Similar to testing a car, a team of researchers at UBC Okanagan has been test-driving a number of mechanical heart valves (MHV)—and the one designed in their own lab appears to outperform the others.
