Does fitness bracelets and smartwatches measures
the pulse rate continuously?

Why is the ECG not measured on a wrist?

It is physically impossible to measure an ECG on just one wrist.

What is the duration of the KeepHealth system?

The continuous operating time of the KeepHealth Wave ECG transmitter is at least 72 hours. It is sufficient to place the Wave on the charger every two to three days for 30-60 minutes in order to be able to record a further 72 hours permanently.

The battery consumption of your smartphone is between 0,8% and 1,2% per hour, depending on the model. Calculated per day, the consumption is ~ 10-15%. This includes the continuous transmission of the ECG via Bluetooth LE to your smartphone as well as all analyses and calculations of your Personalhealth Points (PeP).

In contrast, when measuring at the wrist, movements that are not relevant for activity are often added and falsify the results.

What does the lifestream of my heart mean?

The Lifestream is, so to speak, your personal life flow in real time. Seeing this is one of the most intriguing experiences. You will love it! We have designed the presentation of the Lifestream so that it passes smoothly and gently. At the same time, it also helps to check whether you have put on your chest belt correctly.

How does a good lifestream look like?

This is what your Lifestream should look like. It flow smoothly and evenly past you.

If the lifestream looks like this, you have set up the KeepHealth Wave sensor the wrong way round. Your heart is upside down, so to speak. Simply turn the chest strap with the KeepHealth Wave sensor over and put it on again.

Why does my lifestream look like this?

This is a so-called noisy ECG. For a good ECG signal, a slight moisture film must form between the rubber electrode of the belt and your skin. If you put on the belt, this may take a few minutes, depending on your skin type. If you moisten the rubber electrode with a drop of water, you will get a permanently good ECG signal much faster and thus a nice lifestream.

Why is KeepHealth a consumer product and not a medical device?

We waive the expensive medical approval to offer you a high quality product at a great price. The ECG corresponds to medical quality. The entire development and manufacturing process meets the strict requirements of medical approval.
