Press the button in the center of the sensor until the blue light comes on

Prepare for test

Wash and dry the skin. Hair should be removed.

Remove the paper on the adhesive side of the electrode patch.

Attach the sensor to the center of the chest.

Wait until the sensor is calibrated and connected

The heart rhythm is recorded and analyzed

Use the sensor for at least 3 days

You can now use your phone as usual, but always have it near the sensor during the test period.

Your heart signals (ECG) are displayed in real time during the test by touching the ECG symbol in the upper right corner of the screen

More information about any rhythm disorders can be found by pressing the result button.

The test is stopped by pressing “Stop test”

Order a review of the test results from our heart specialists or share the results with your doctor

Press the result button and follow the instructions

The ECG247 heart sensor detects the cardiac electrical signals (ECG) and analyzes them for rhythm disorders. Heart rhythm disorders are a common term for all deviations from the normal heart rhythm (sinus rhythm). Heart rhythm disorders can cause rapid, slow or irregular heart rhythm. You may experience rhythm disorders such as irregular heartbeat, palpitations, dizziness or syncope.

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. If a blood clot forms in the heart, there is a chance that it will loosen and cause a stroke.

If the test result shows that you have a possible heart rhythm disorders, we recommend that you have the registration assessed by a physician. You can either share the test with your GP or you can order a review of the test from our cardiologists.

The heart signals have different shapes and sizes in different people. We cannot guarantee that this test finds all different rhythm disorders in everyone. Use of sensor and associated software is therefore at your own risk. Any heart rhythm disorders must be confirmed by a doctor.

The sensor may fail to recognize rhythm disorders if you have a pacemaker. if you have a pacemaker, a doctor should evaluate your recordings.

The sensor cannot look for signs of myocardial infarction. Always contact a physician if you have symptoms from your heart.

The sensor should not be used in children <10 kg.

Test duration
For the most accurate results of this test, we would like you to test for at least 3 days. You can stop it before 3 days, but then you have less heart rhythm recordings. We recommend testing for 7 days if this does not cause you any problems. If you forget to stop the test, it will automatically be stopped after 14 days.

You can take a shower with the sensor, but avoid bathing and swimming. Some types of clothing, such as technical training clothing over the sensor, may interfere with the recording. This is seen as interference in the ECG view in the app, but is not dangerous. This usually disappear after a short time. Exercise involving the use of arm and chest muscles can also interfere with the recordings, but the signals usually return to normal after exercise.

If desired, you can save a recording of your heart rhythm at a specific time by briefly pressing the button in the middle of the ECG247 sensor.

Some people may react with itching and skin irritation under the electrode. This is not dangerous, but may be uncomfortable.

Please note that the sensor causes increased data traffic on your mobile phone. We recommend use of Wi-Fi network if possible.

The sensor can be used many times — take good care of it.

We recommend regular testing. New ECG247 electrodes can be purchased at

The sensor must be kept out of reach of children.

The battery has to be removed from the electrode and sorted as special waste.
