The Kardia Bracelet Makes Apple Watch a Medical Heart Rate Monitor

In time for the introduction of the ninth Apple Watch Nike +, there is a new bracelet for the Smartwatch market leader. The US startup AliveCor, managed by the former Google engineer Vic Gundotra, wants to equip the Apple Watch with a medically accurate pulse measurement. First of all, the question arises why a potential buyer should buy an expensive bracelet to measure the heart rate (the price is settled at over 200 euros), although the Apple Watch itself has nevertheless installed a neat optical pulse meter.

The answer to this question lies in the uniqueness of this pulse meter. The cardia band is unique in that it is to recognize hereditary diseases. The measurement not only focuses on the number of beats per minute, but also analyzes the regularity and other factors that are important to the health of the heart.


Technically, the pulse measurement by the cardia band is also considerably more complex. While the Apple Watch itself, like most fitness bracelets or smartwatches, used optical pulse measurement to measure blood activity in the veins, Kardia uses ECG technology. In this very accurate method, the electromagnetic activity of the heartbeat is measured.

Thus, the Kardia tape would be the first commercial wearable using this technology. With the associated AliveCor app, which can be synchronized with AppleHealth, the pulse values ​​can then be analyzed and assessed for health. From the beginning of November, the bracelets will be available in 38 and 42 millimeter width versions.
