Diseases of the heart and circulation are the most common cause of death - even before cancer! So we should pay a lot of attention to the health of the heart. But how? Everyone knows the rise of pulse when the doctor measures the heart function, for example, with the electrocardiogram (ECG). It would be better to check the heart function unnoticed, e.g. when brushing your teeth in the
