- People with AFib reviewing Apple Watch records
- Worth noticing
- The author distinguishes watch-issued burden estimates from raw-beat counts and cautions that a one-person record cannot establish population effects.
Field notes
The pages pair each finding with its date range and source data, then give step-by-step filters intended to let readers repeat counts on their own Apple Watch export. The author reports five years of records, including 112 ECGs and 1,316 nights, and explicitly limits conclusions to one person; the site says its contents were not doctor-reviewed and are not medical advice.
