Apple Watch Heart Rate sensor can detect COVID-19

That's from a recent report of Mount Sinai researchers, the Apple Watch will accurately predict positive COVID-19 with the heart rate sensor for up to 1 week consecutive to the PCR-based nasal swab check.


Recently, the article 'Warrior Watch Thesis' was published in the Journal of Medical Science. Some hundred health care employees from Mount Sinai have been monitored and gathered using a dedicated Apple Watch and iPhone program. For a period of months, participants had to make clear statements about the potential symptoms of coronavirus and other factors, including stress, every day.

Data collection lasted for several months from April to September. In analysis, the key predictor of tension on the nervous system was the variability in the heart rate (HRV). These findings were then associated with recorded signs of illness such as fever, aches, sinus infection and taste and lack of smell.

In addition to identifying illnesses up to a week before testing, the Warrior Watch study also showed that HRV habits of participants improved very soon following diagnosis and returned to normal for around a week or two weeks after testing positive.


The team claims that these observations will help forecast outcomes and remotely differentiate patients from those at risk without having to conduct a medical check-up or a swab examination. Study is now being extended to cover other wearables of various brands.
