The quick check is a snapshot of heart rate variability. At the moment of a measurement, the person taking the measurement can have the HRV values ​​of a 50-year-old. 3 hours later he could have the HRV values ​​of a 25 year old. This can have very different reasons. For example:
During one of the measurements, the person taking the measurement may not have had stable measurement conditions: coughing, swallowing, moving, etc.
He may have eaten something in the last 1-2 hours before the first measurement He could have played sports
He could have been upset about something during the first measurement
He may have recovered in the meantime
That's why the quick check is not as accurate as the normal measurement. For the quick check, the Vitalmonitor has no way of adapting to the body of the person taking the measurement. To ensure that quick checks are still as meaningful as possible, it is important to take measurements while sitting and resting. It is best for the person taking the measurement to sit down for a minute, come down and then start measuring!
