The ECG app packs a high-performance ECG sensor module, which provides single-lead ECG measurements, real-time analysis, and sinus rhythm, atrial fibrillation*, to proactively keep you informed about significant risks related to heart health. The new and improved electrode technology offers greater accuracy and responsiveness in ECG signal collection, with the addition of PVD-coated electrodes on the curved, transparent sapphire case, resulting in a comfortable, snug fit on the skin. Simply touch the electrode on the side for 30 seconds, the real-time result is displayed on your watch after the measurement.
