You can check the ECG test results for the current day from the Diary. Tapping the card opens the detailed test result
view.
In the detailed test result view, you will see the following results in addition to the results displayed on the watch:
l PAT at relaxation and PAT at contraction: Pulse arrival time (PAT) refers to the time it takes for the pressure wave
generated by your heartbeat to reach your wrist. PAT at contraction and PAT at relaxation are measured at two
different time points of the pressure wave.
l ECG graph: In the ECG graph, the spikes represent your heartbeats. You can scroll the graph vertically by swiping.
You can export the ECG test result to a PDF file. Tapping the list icon opens your previous ECG test results in the calendar
search view.

SpO2 measurement
The SpO2 measurement feature uses pulse oximeter technology to estimate the amount of oxygen in your blood. Your
body needs a constant supply of oxygen to perform properly. Your blood oxygen level (SpO2) shows how much oxygen
your blood carries compared to its full capacity (100%). When you're at sea level and at rest, SpO2 between 95 % and 100
% is considered normal. Because of lower atmospheric pressure, SpO2 is lower at higher altitudes.
You can measure SpO2 conveniently from your wrist whenever you want in just 45 seconds. Regular SpO2 measurement
allows you to monitor your usual SpO2 level in everyday life under normal circumstances. Knowing your usual level can help
you understand how your body adapts to certain situations, such as high altitudes. If you're training at varying altitudes, you
can use this measurement to monitor how your SpO2 changes and your body adapts to new altitude.
