Apple Watch has an ECG app, sleep tracking, blood oxygen level monitoring — or at least, it probably will again — and many more health-related sensors and capabilities.

According to the UK’s tabloid newspaper The Sun, Sam Adams, a woman from Brighton, has now been recounting how a series of Apple Watch alerts in 2022 finally led her to seek treatment. They had each concerned an unusually low heart rate, but initially Adams had ignored them.
