What is an Electrocardiogram (ECG)?
An Electrocardiogram (ECG) is a test that measures the electrical activity of the heart and records the information on a graph. An ECG is currently the best way to detect irregular rhythms.
The Samsung Health Monitor ECG app detects ECG signals (similar to a Lead I ECG) with the help of your Galaxy Watch's ECG sensor and determines whether atrial fibrillation or normal sinus rhythm is present. The Samsung Health Monitor ECG app creates, records, saves, and exports ECG data.¹, ²
How do I measure my ECG with the Samsung Health Monitor App?
Pair your Samsung devices
In order to take an ECG with this app, you must pair your Galaxy Watch with a compatible Galaxy smartphone2 using the following steps.
1) Ensure that your Galaxy Watch supports the Samsung Health Monitor.³
*Supported watches: Galaxy Watch3, Galaxy Watch Active2 and later released Galaxy Watch and Active models, excluding Galaxy Fit.
2) Ensure that your Galaxy Watch is paired via Bluetooth with your Galaxy smartphone.
3) If Samsung Health Monitor is installed on your Galaxy Watch, open the app and follow the on-screen set-up instructions.³
Preparing to take an ECG
Use the following steps when taking an ECG to get the best and most consistent results.
1) Wear the Galaxy Watch snugly on your wrist.
2) Make sure that your wrist (the skin area that comes in contact with the watch sensor) is not too dry.
3) Avoid hard exercise from 5 minutes before the measurement.
4) Take measurements sitting in a chair with your back properly supported and with hands and arms resting comfortably on the table.
5) Do not move your arms and fingers or speak during the measurement.
Recording an ECG using your Galaxy Watch
Once your device is set up, you're ready to take an ECG.
1) Open the Samsung Health Monitor app on your Galaxy Watch.
2) Make sure the Galaxy Watch is snug on your wrist.
3) Rest your forearms comfortably on a table, then rest a fingertip of the opposite hand lightly on the Galaxy Watch’s top button for 30 seconds. Remain still and do not talk while your Galaxy Watch takes the measurement. When the recording process has finished, the ECG results will appear on your Watch.
Note: Don't press the top button during recording, as this will stop the recording.
4) Scroll up and down to see your ECG result. If you are experiencing symptoms, tap Add, and on the Symptoms screen scroll through the list and tap each symptom you are experiencing.
5) Tap Save to add the symptoms to your ECG report and to return to the Results screen.
6) Tap Done to return to the Start screen. You can review your ECG report in the ECG Monitor app on your phone. (Note that syncing requires that the watch and phone are paired using Bluetooth.)
Reviewing your ECG reports
After you take an ECG, the ECG data is synced to the paired Galaxy smartphone where a PDF report is created.
1) Your ECG analysis is sent from Galaxy Watch to your Galaxy smartphone shortly after measurement.
2) On the phone app, you can retrieve detailed results transmitted from your Galaxy Watch and you can see the classified results as follows:
∙ Sinus Rhythm: A sinus rhythm is when the heart beats in a consistent rhythm. This occurs when the heart’s upper and lower chambers beat in sync. A sinus rhythm result is based only on that particular ECG recording, and doesn’t mean your heart beats uniformly all the time. Also, a sinus rhythm result does not guarantee that you are not experiencing arrhythmia or another health condition. If you are not feeling well regardless of your result, contact your doctor.
∙ Atrial Fibrillation: Atrial Fibrillation, or AFib, is when the heart beats in an irregular rhythm. This occurs when the heart’s upper chambers beat out of sync with the lower chambers. AFib is the most common form of an irregular heartbeat. If not treated, it can lead to blood clots, stroke, heart failure, and other health problems.
∙ Inconclusive: An inconclusive result means that the ECG recording could not be classified. This could happen if:
- The heart rate during the recording was less than 50 bpm.
- The heart rate during recording was greater than 100 bpm and the rhythm was not AFib.
- The heart rhythm was AFib and the heart rate was greater than 120 bpm. The heart rhythm was neither sinus rhythm nor AFib.
If you get this result repeatedly, contact your doctor.
∙ Poor recording: A poor recording result means Samsung Health Monitor was not able to analyze the data. A poor recording usually happens because your body moved during recording, or the Galaxy Watch didn't have enough skin contact with your wrist or finger. If you get this result repeatedly, see the Troubleshooting section in the Instructions For Use document.
Things you need to know before using the ECG app:
1) The ECG app should not be used for any diagnostic purposes. The ECG app cannot diagnose cardiac conditions or look for signs of a heart attack.
2) The ECG app is not meant to replace traditional methods of diagnosis or treatment by a qualified healthcare professional. If you think you are having a medical emergency, contact your local emergency services immediately.
3) DO NOT change your medications or dosage without first consulting your doctor.
4) DO NOT interpret the results or take clinical action based on the ECG app measurements without first consulting with a qualified healthcare professional.
5) DO NOT use the ECG app if you have an implanted pacemaker, implanted cardiac defibrillator, or other implanted electronic devices.
6) DO NOT use the ECG app if you have known arrhythmia other than Atrial Fibrillation.
