Conventional wristwatches are worn with pleasure. Smartwatches have not yet outstripped their predecessors. However, the digital models have some additional functions – which can detect heart problems early on.
Some models can be used to obtain an ECG, for example. A smartwatch can therefore be able to measure the electrical activity of the heart. Cardiac arrhythmias can also be detected by some variants. Now researchers have even reported a special model that is supposed to make heart blood flow disturbances visible. Many smartwatch models were analyzed by stiftung warentest in 2019 – you can find the results here.
