Kardia FAQs

Is Kardia FDA-Cleared?

Yes! Kardia is FDA cleared for individual use and for those weighing at least 10kg (22 lbs). It is also CE marked. Kardia is available in the US, UK, Ireland, India, Australia and New Zealand for over the counter use.

What are the AF, Normal and Interference Detectors?

AliveCor has developed three FDA-cleared detectors or algorithms. These detectors are only appropriate for use on Lead I.

The Normal detector will notify you when no abnormalities are detected by displaying the message “Normal. No abnormalities were detected in your EKG.” This means that your heart rate was between 50-100 beats per minute, there were no or very few abnormal beats, and the shape, timing and duration of each beat is considered normal. Remember that there is a wide range of “normal” variability among different individuals, so the Normal detector has been designed to be conservative. Also, if you have been diagnosed by a physician with a condition that affects the shape of your EKG, are experiencing an arrhythmia or took a poor quality recording, it is unlikely that you will be notified that your EKG is normal.

The Interference detector will notify you when the recording is unreadable by displaying a message that says “Unreadable. There was too much interference in this recording. Try to relax and hold still, rest your arms or move to a quiet location.” Once you’ve made these changes you can go ahead and take another recording. Other best practices to get a high quality recording include:

  • Ensure your smartphone or tablet is not plugged in, charging or syncing during recording.
  • Keep your Kardia electrodes clean using an alcohol-based sanitizer.
  • Apply a water-based lotion to your hands prior to taking an EKG recording if your hands are very dry.
  • Enable the “enhanced filter” on your smart phone or tablet.

The AF detector will notify you to the presence of atrial fibrillation with 97% sensitivity and 98% specificity. If AF is detected, you will see the message “Possible AF Detected.” This result is not a diagnosis, only a possible finding. We recommend sending it AliveCor’s EKG analysis service for review, or sharing it with your doctor or medical professional.

Note that the EKG recording must be 30 seconds in length for the detectors to function.

What does it mean if my EKG is Unclassified?

You may receive a message that says “we could not classify this EKG.” This means that the detectors could not classify your EKG recording as Normal, Unreadable or AF. There could be many reasons why you received this message. You have the option to send your EKG for analysis directly from Kardia, or share it with your doctor or medical professional. If you prefer not to receive this message, you can disable the “Unclassified Message” in the Kardia settings.

What do I do if I am unable to take a recording?

If Kardia is not responding or will not take a recording, you may need to replace the battery. Expose the battery door at the back of Kardia Mobile and remove Kardia Mobile from the plate. Remove the battery door, the replace the used battery with a new 3V coin cell battery matched to your model. Orient the battery with the positive terminal up so you can see the writing. Remove the protective sticker from the battery if applicable.

What is the Clinician Review?

You may send an EKG recording out for review by a board certified cardiologist or trained cardiac technician for an out-of-pocket fee. A comprehensive review and recommendation by a board certified cardiologist is $19 with a response within 24 hours, and a quick interpretation by a trained cardiac technician is $9 with a response within 1 hour.
