With the release of the Galaxy Watch 3, the electrocardiogram (ECG) measurement feature has been activated, allowing users to view the results on the smartwatch and the Samsung Health Monitor app.

[Asia Economy Reporter Han Jinju] Why do we still feel tired even after sleeping? Did we really run properly when we were sweating profusely? The Galaxy Watch3 is a smart watch and exercise mate that answers such questions with scores. Equipped with blood pressure and electrocardiogram (ECG) measurement functions, it positions itself as a daily doctor for those with hypertension and heart disease who need to manage their numbers carefully.

With the release of the Galaxy Watch3, ECG measurement became possible. When using it for the first time, you need to install the Samsung Health Monitor app on your smartphone, wear the Galaxy Watch3 on your left arm, and place your finger on the button (crown) to measure three times for 30 seconds each. From the second time onward, a single measurement provides the average heart rate and type value. The result types are displayed as one of four: sinus rhythm, atrial fibrillation, inconclusive, or poor signal. Sinus rhythm means the heart is beating regularly. Atrial fibrillation is an irregular heartbeat symptom that appears with chest pain or pressure, dizziness, or skipped heartbeats.

How to Measure Electrocardiogram with Galaxy Watch3

To use the blood pressure measurement feature, a cuff blood pressure monitor is essential. Enter the reference value measured with the blood pressure monitor, then measure separately three times with the Galaxy Watch3 to receive the calibration value.

Blood pressure measurement requires simultaneous measurement with a blood pressure cuff device and the watch. After entering cuff device measurements three times, the watch additionally measures correction values and provides a comparative analysis result. Before measurement, a notice appears stating, "This is for reference only; do not interpret the results arbitrarily or proceed with medical treatment." When measured directly, results were similar to the cuff device values. The Health Monitor app displays the measurement values and pulse rate together and allows checking trends over time, making it convenient to monitor changes.

The Galaxy Watch3 is even more useful for those who enjoy running. After selecting running mode and finishing exercise, detailed analysis is provided, including the degree of left-right asymmetry, ground contact time, vertical oscillation, and regularity stiffness. It informs the exercise pace every 1 km and encourages exercise by pausing when you stop. The watch screen shows duration, pace, and heart rate simultaneously.

Galaxy Watch3 Running Features

You can also check detailed analysis results of distance, speed, and running in the Samsung Health Monitor app.

The sleep monitoring function is also upgraded, allowing you to know how well you slept with a score. The sleep score is divided and displayed by awake time during sleep, REM sleep, light sleep, and deep sleep. The reporter, who has no insomnia, received a score higher than the standard for gender and age. Measurements showed that deep sleep time was longer on weekends than weekdays. Tossing and turning is recognized as waking during sleep.

The Galaxy Watch3 (41mm) is thicker and heavier than the Galaxy Watch Active2 but feels much more luxurious thanks to the bezel, color, and leather strap. The rotating bezel makes it easy to select desired functions even with a small watch screen. It is perfect for the 20s and 30s generation who enjoy exercise as well as middle-aged and older adults who need blood pressure and ECG measurements. The price starts at 429,000 KRW for the Bluetooth model (41mm) and 495,000 KRW for the LTE model (41mm).
