Use the Samsung Health Monitor app on your Galaxy watch

Galaxy Watch3 with Health Monitor app running

There’s a new app available on your Galaxy watch called the Samsung Health Monitor app. You can use the app’s features to record your electrocardiogram data, to determine your heart's rhythm, and share the results with healthcare professionals, so you’ll be able to understand more about your health. Once you’re finished recording, you can view, save, and share your data on your Galaxy phone.

Caution: The information gathered from this device, Samsung Health, or related software is not intended to diagnose, cure, mitigate, treat, or prevent disease or other conditions. The ECG app is not intended for users under 22 years old or with known arrhythmias, other than atrial fibrillation, and is not intended to replace traditional methods of diagnosis or treatment. Users should not interpret or take clinical action based on the device output without consultation of a qualified healthcare professional.

Tips for recording your ECG

Note: The Samsung Health Monitor app requires a Galaxy Watch Active2 or Watch3 on the most recent software (Tizen 4.0.0.8 or higher), or a Galaxy Watch4, paired with a Galaxy phone running Android 7 (Nougat) or later.

The ECG feature of the Samsung Health Monitor app records your heart’s electrical activity in a certain way. Here are a few helpful tips to follow.

When you are recording, make sure:

  • Your fingertip fully covers the top button on your watch.

  • You do not press the top button on your watch.

  • Your finger is resting lightly on the top button for the 30 seconds it takes to do the recording.

  • You do not move your arms or talk.

Set up the Samsung Health Monitor app

Once your phone and watch have been paired, you can start setting up the ECG feature with the Samsung Health Monitor app. The Samsung Health Monitor App cannot be downloaded separately. It is only available once your Galaxy phone and compatible watch are paired and all software is up to date. If the app still is not showing, there are some additional steps that can be performed.

Note: The Samsung Health Monitor app requires a Galaxy Watch Active2 or Watch3 on the most recent software (Tizen 4.0.0.8 or higher), or a Galaxy Watch4, paired with a Galaxy phone running Android 7 (Nougat) or later.

  4. Fill out the information to create your profile, and then tap Continue. The app will begin searching for a compatible smart watch.

  5. When your watch is discovered on the phone, tap Get started. If your phone is having trouble discovering your watch, open the Samsung Health Monitor app on your watch. Allow the permissions, and then tap Open phone app. Your phone should then discover the watch.

  6. You will be prompted to go through the app’s initial setup. Follow the on-screen prompts and review the information shown. Tap Done when you’re finished.

Record an ECG on your Galaxy watch

Note: The Samsung Health Monitor app requires a Galaxy Watch Active2 or Watch3 on the most recent software (Tizen 4.0.0.8 or higher), or a Galaxy Watch4, paired with a Galaxy phone running Android 7 (Nougat) or later.

Just put your watch on your wrist and open the Samsung Health Monitor app to begin recording your ECG. Make sure your watch and phone have been paired using Bluetooth and the Galaxy Wearable app, so you can sync your data after the scan.

  1. Before you can record an ECG, you will need to install the Samsung Health Monitor app on your phone.

  2. Open the Samsung Health Monitor app on your watch, and make sure your watch is snug on the wrist selected during the setup process.

  3. Read the information and then tap OK.

  4. Rest your forearms comfortably on a table. Then, using your opposite hand, lightly rest one of your fingers on the watch’s top button for 30 seconds. Remain still and do not talk while the watch takes your measurement.

Possible results

Note: Certain physiological conditions can prevent some people from having a strong enough signal for the Samsung Health Monitor app to detect and analyze.

There are a few possible results after recording your ECG: Sinus Rhythm, Atrial Fibrillation, and Poor recording. You may also receive an Inconclusive result; there is more in-depth information about this result in the next section.

  • Sinus Rhythm: If you receive this result, your heart was beating at a regular rhythm with a heart rate of 50-100 BPM (beats per minute).

    Caution: A Sinus Rhythm does not guarantee that you are not experiencing an arrhythmia or another health condition. You should contact your doctor if you are not feeling well. 

  • Atrial Fibrillation (AFib): During the recording, your heart was beating at an irregular rhythm with a heart rate of 50-120 BPM. You should contact your doctor if you receive this result.

  • Poor recording: A poor recording result means that the Samsung Health Monitor app was not able to analyze your data. You may receive a poor recording if you moved your body during a recording or if your watch did not have enough skin contact with your wrist or finger. There are a few things you can try in order to receive a proper recording:

    • Clean your hand, wrist, and the back of the watch.

    • Moisturize your hand and wrist with lotion.

    • If your skin is cold, remove the watch and gently rub your wrist to warm up your skin. Then, put the watch back on and try recording again.

    • Make sure the watch is snug on your wrist, and rest your forearms comfortably on a table or flat surface when recording.

    • For better skin contact, try wearing the watch slightly away from your wrist bone and toward your elbow.

  • Inconclusive: This result means that the ECG recording could not be classified because the heart rate was either too high or too low. Please see the next section to learn more about inconclusive results.

Inconclusive results

Note: If you receive an Inconclusive result repeatedly, contact your doctor.

An Inconclusive result could potentially be caused by a high or low heart rate, or another heart rhythm that is not classified as Atrial Fibrillation or Sinus Rhythm. A high heart rate can be normal, such as during exercise or emotional stress. It can also be a response to dehydration, fever, infection or other conditions including Atrial Fibrillation or other arrhythmia. 

A low heart rate can be normal as well. Reasons for a low heart rate include certain medications or conditions associated with abnormal electrical activity in the heart. If you’d like to record your ECG again after an Inconclusive result, you should stay still for about 5–10 minutes before doing so.

The following are possible reasons for an Inconclusive result:

  • Your heart rate was greater than 120 BPM, and your heart rhythm is Atrial Fibrillation.

  • Your heart rate was less than 50 BPM, resulting in a low heart rate.

  • Your heart rate was greater than 100 BPM, resulting in a high heart rate, but your heart rhythm is not Atrial Fibrillation.

  • Your heart rhythm was neither Sinus Rhythm nor Atrial Fibrillation.
