Understanding your heart rhythm

This library is general education, not a diagnosis. It doesn't reflect your specific report — talk to your doctor about what your results mean for you.

What your wearable can't tell you

A watch or ring is built to notice something and alert you. It isn't built to measure it. That gap is the whole reason this exists.

Your wearable

5-day heart monitor

Checks in now and then, mostly when you're still

Records every beat for five days straight

Tells you something looked off

Measures how often, how long, and how fast

Can't tell whether it explains how you felt

Matches each episode to the symptoms you logged

Ends with a notification

Ends with a physician-reviewed report your doctor can use

Questions it can actually answer

✓Was it really an arrhythmia?
✓Which type of rhythm is it?
✓How much of the time is it happening?
✓Do my symptoms line up with it?
✓Is it happening while I sleep?

The monitor produces the measurements. A physician reads them and explains what they mean for you — the device itself never diagnoses.
