Measuring ECG with Kardi Ai

Do you want to obtain accurate and reliable ECG recordings using the Kardi Ai chest strap? Follow this step-by-step guide for successful measurement.

To record and process it, it is essential to have Bluetooth turned on and at the same time have an active internet connection, whether via mobile data or Wi-Fi.

When to measure ECG

• You can take measurements at any time - both during health issues and without them as part of cardiovascular disease prevention.

• We recommend taking measurements at least 3 times a week.

• Each measurement should last at least 3 hours.

• The total length of your weekly measurements should exceed 7 hours.

• Always measure during the time of difficulties.

• At least once a week we recommend taking a measurement during sleep (all night).

The maximum duration of a single ECG recording is 24 hours.

• To prevent skin irritation, the skin needs to rest.

• The recording is evaluated after the recording ends, so processing a longer recording may take several minutes.

For the correct transfer of measurement data to your mobile phone, the phone needs to be in the immediate vicinity of the chest strap during the recording.

Measurement procedure

1. Put on the Kardi Ai chest strap The chest strap does not need to be turned on in any way; it activates itself 10 seconds after being put on the body.

6. Recording health difficulties (optional) If you experience health problems during the measurement, mark them using the Record health difficulties button.

7. Ending the recording

   To end the recording, press the Stop ECG recording button. ⚠️ If you do not end the recording using the Stop recording button in the app, the measurement data will be lost.

Overview of recordings

After evaluation, a colored bar according to our traffic light will appear next to your recording, and the evaluation is ready.

For more information about the color traffic light of evaluated recordings, continue to Measurement Evaluation Traffic Light.

If you feel unwell in any respect, consider consulting a doctor immediately regardless of the Kardi Ai measurement result. The result of the ECG recorded from the chest strap cannot under any circumstances be used to detect myocardial infarction or generally a worsening of the blood supply to the heart. A negative finding says nothing about the reason for any possible chest pain.
