Frequently Asked Questions (FAQ)

Heart rhythm disorders are a common term for all deviations from the normal heart rhythm (sinus rhythm). Many heart rhythm disorders are harmless, while others require medical treatment. Heart rhythm disorders can cause rapid, slow or irregular heart rhythm.

Cardiac arrhythmia can be experienced as irregular heartbeat, palpitations, dizziness or sometimes as fainting. A frequent heart rhythm disorder is atrial fibrillation.  In atrial fibrillation the heart beats irregularly and often too fast. Atrial fibrillation increases the risk of a blood clot forming in the heart. Such a blood clot can follow the large blood vessels to the brain and cause a stroke. An anticoagulant drug can prevent blood clots in atrial fibrillation. Contact your doctor if you have atrial fibrillation.

The ECG247 app can be downloaded for free on your mobile phone from AppStore (iPhone) or Google Play (android).

Yes. The ECG247 heart sensor records the heart rhythm for analysis. Diagnosis and treatment must be prescribed by a physician.

Please clean the skin over the sternum (middle of the chest). Any hair must be removed. Do not use moisturizer. The skin must be completely dry before the sensor is attached.

Download the ECG247 app and follow the instructions. We also recommend that you watch the informational video before starting the test.

Make sure your phone is connected to the internet and try again.

Check that you have followed the User Guide. Sensor must be connected to the electrode patch and the sensor must be light blue before connecting. Check that Bluetooth is enabled for ECG247 in your phone’s settings and that you answered “Yes” to the question of allowing for Bluetooth connectivity. If this does not allow for connecting to the sensor, delete and re-install the ECG247 app. If the issue persists, follow the same procedure on another smart phone.

The sensor should be attached to the center of the chest with the sensor part up.

The ECG247 system automatically detects all common cardiac arrhythmias such as atrial fibrillation, atrial flutter, supraventricular tachycardia, ventricular tachycardia and pauses. In addition, the system also detects extrasystoles and sinus arrhythmia.

Electrical noise can affect the automatic interpretation and lead to misclassification. All rhythm disorders must therefore be confirmed by a physician. You can easily order a cardiologist assessment in the online store or you can share the recording with your GP.

The heart signals have different shapes and sizes in different people. Therefore, we cannot guarantee that the ECG247 system will detect all rhythm disorders. All use is at your own risk.

Yes, the sensor can be reused many times. Take good care of it. New electrode patches can be ordered in the online store. 

Yes, both the electrode patch and the sensor can withstand showering, but you must avoid swimming or taking a bath where the sensor is submerged in water/liquid.

The ECG247 sensor is approved for all users weighing more than 10 kg.

Ensure that children do not put the sensor or parts of the sensor in their mouth.

No, the system is designed to detect heart rhythm disorders.

Always consult a doctor about heart symptoms.

Yes, the sensor communicates continuously with the phone and notifies you if the sensor is suddenly disconnected. The sensor should reconnect to the smart phone automatically. If the sensor does not reconnect, the test must be stopped and restarted in the app. It is not necessary to remove the sensor or electrode patch.

Yes, but this is rarely necessary since pacemakers normally monitor the heart rhythm.

Short rhythm disorders are common and often harmless, but possible rhythm disorders should always be considered by a physician. Order a cardiologist assessment in the online store or share the test with your doctor in the ECG247 app.

No, the electrode patch including the battery is for single use. The battery is easily separated from the patch and recycled according to local guidelines. 

The patch is intended for single use. With repeated use, the heart signals will not be captured correctly and the interpretation will be incorrect. New electrode patches can be ordered from the online store

We recommend using the sensor for at least 3 days. You can stop the test at any time, but the shorter the test period lasts, the less heart rhythm recording there is to analyze. It is up to you as the user to decide the duration of the test. The sensor will automatically stop collecting data after 14 days

Some types of clothing, such as technical exercise clothing over the sensor, may interfere with the recording. This is seen as “noise” in the ECG view in the app, but is not dangerous. The problem usually disappear after a short period of time. Exercise involving the use of the arm and chest muscles can also interfere with the recordings, but the signals usually return to normal after exercise. Such disturbances may cause the rhythm indicator to change color and indicate that a possible rhythm disturbance has been identified. In such cases, the app’s rhythm indicator can be reset by stopping the test and then starting a new test without removing the sensor.

Yes, reattach it in the same way as when you started the test. It is important that the arrow points to the closed lock symbol. The test continues automatically when the sensor is reconnected. If this does not happen, you can stop the test in the app and then start another test without removing the electrode patch.

Yes, you can save a recording of your heart rhythm at a specific time by briefly pressing the button in the center of the sensor.

Some people may react with itching and skin irritation under the electrode patch, as with all other plastics. This is not dangerous, but may be uncomfortable. For troublesome symptoms, the test should be stopped and the patch removed. Contact a physician if needed.

Yes, taking an ECG247 test increases data traffic from the mobile phone. We recommend connecting to a Wi-Fi network if possible

Regular testing, preferably annually, with the ECG247 sensor is recommended if you are at risk (over 65, have diabetes, high blood pressure, previous stroke or cardiovascular disease).

The sensor can be used many times – take good care of it. New ECG247 electrode patches can be ordered from the online store.

Yes, but the sensor can only be connected to one smart phone at a time. When using the sensor with two smart phones, ensure that the Bluetooth connection between the sensor and the original smart phone device has been disabled/deleted in the smart phone settings

The sensor can be washed with a slightly damp cloth. Disinfectant can also be used.

Note: Do not immerse the sensor in liquids.

ECG247 increases power consumption – remember to charge your mobile phone frequently. If the phone has completely shut down, open the ECG247 app and check if the test starts up again. If it does not restart, please follow the instructions in the app. Remember that you can always stop the test and start another test without removing the electrode patch from the body. This resets the sensor and the rhythm indicator.

Press “Stop test” in the app.

Remove sensor and electrode patch.

The sensor can be used many times – take good care of it. New electrode patches can be ordered from the online store.

Cardiologist assessment is easily ordered in the online store.

The test is assessed by our experienced Norwegian cardiologists. The report is available in the app upon completion.

Note that only results from the ECG247 test are evaluated and described. Any further examination and treatment must be done by your own doctor.

Your unique test ID must be registered when ordering a cardiologist assessment. The unique test ID for each test can be found in the ECG24 app under “My previous tests”
