Withings introduced multiple wearables at CES today, including a new watch that can take electrocardiograms (EKGs). The Move ECG is part of the new Move line, and it includes an EKG to measure heart rhythm patterns.

The Move ECG features three electrodes to take measurements: two inside the back of the watch and a third in the bezel. Users touch both sides of the bezel to take a measurement, and the watch will vibrate when it has a reading. All of the data can then be found in the company’s companion app, Health Mate.
