Announced at Samsung Unpacked earlier in August, the Galaxy Watch 4 brings a flagship Android smartwatch experience to a starting price of $249. Since its first generation, the device has come a long way in providing health-related metrics. But at a reduced price, it wouldn't be shocking if Samsung decided to cut features, so does it have ECG sensors to record an electrocardiograph like its competitors? The answer to this question is, Yes, the Galaxy Watch 4 does have a sensor for ECG.
Recording an ECG is done via the BioActive sensor, which Samsung says is a combination of three units, two of which were responsible for measuring heart rate and electrical impedance, and a new third unit, which will calculate body composition.
