The ECG function is basically integrated in the Huawei GT5 Pro (46 mm) and enables the recording of real-time heart data for the early detection of common heart problems. However, the availability of the ECG function is country-specific and there is no clear indication that it is officially enabled or authorised in Switzerland. Huawei refers to a list of supported countries for the ECG app without explicitly mentioning Switzerland. Therefore, the use of the ECG function may be restricted or not officially available in Switzerland.
