As part of the update of the older model of smart watches Fitbit Sense, the ECG function has become available to users in the US, UK and Germany. The Fitbit Sense smartwatch was announced in August for $ 329. The model has a wide range of functionality for tracking the user’s health, including the ability to control temperature, oxygen saturation levels, and high-precision heart rate control. The watch claimed to have an ECG function, but at launch the company did not yet have FDA approval, which it has now received. To record an ECG, the user needs to put his fingers on both sides of the stainless steel ring, while reading the heart rate parameters. This data is recorded in the proprietary ECG application, which users will receive after updating their watches or can install themselves by downloading it from the official Fitbit website. The watch is already available for purchase in the United States, in Europe it will appear on October 16.
