Heart Rate

Heart rate is the number of heart beats per time. The usual unit for this is bpm (beats per minute).

In a healthy person, the heart rate measures 50 to 100 beats per minute at rest. The maximum heart rate indicates how many beats per minute can be achieved with maximum physical effort. The maximum heart rate is individual and can be measured using performance diagnostics.

How does our sensor technology measure?

The sensors in all our devices operate with an optical measuring method. This works very much like the finger clip sensors used in hospitals. The PPG signal is derived with the aid of optical measurement technology. The heart rate can then be determined from this signal.

Studies

For all important parameters, extensive studies were carried out in cooperation with renowned partners and were statistically evaluated. Medically approved standard measuring instruments were used as a reference.

Study Management Reference Number of Subjects Data in Hours Mean Error Standard Deviation
Uniklinik Bonn ECG 85 940 + 0,79 bpm ± 2,17 bpm
TU Munich ECG 10 10 + 0,76 bpm ± 1,61 bpm
