Heart Health Monitoring

Optical heart rate sensor
The optical sensor keeps tabs on heart rate consistently, while also conserving battery life by activating periodically around the clock. A notification can be sent to the user in the case of a high or low resting heart rate episode. Continuous heart rate monitoring is activated and recorded when using Workout Mode.
Proactive rhythm monitoring
ScanWatch monitors heartbeat automatically so it can send notifications if irregular rhythms are detected it will then advise the wearer to record an electrocardiogram (ECG).
Medical-grade SpO2
To deliver the percentage of blood oxygen, or SpO2, ScanWatch uses a multi-wavelength PPG sensor to emit and measure red and infrared reflections of blood vessels in the wrist. Normal SpO2 values vary between 90 and 100%, and readings appear on the watch and in the app.
ECG readings
An ECG is the best way to detect atrial fibrillation (AFib), a highly prevalent heart arrhythmia. AFib often goes undiagnosed because it can show no symptoms and/or not be present during doctor’s visits because the episodes can be intermittent.
Share with a doctor
All heart health data is compiled in the app and can be easily shared with a doctor, health coach, or loved one with a few taps via the Health Report feature.
