4.   I have a pacemaker; can I still use the Mobile ECG?

5.   How do I access my account from a computer?

Go to www.alivecor.com

Click "SIGN IN" in the upper right corner

Enter the same email address and password that you use to log into the Kardia app on your smartphone or tablet


6.   What is the length of the recording? Can this be used for continuous monitoring?

The Kardia can be used to record for 30 seconds, 1 minutes, 2 minutes, 3 minutes, 4 minutes, or 5 minutes. It is not intended for long term monitoring, but rather for conveniently and instantly capturing short ECG rhythm strips.


7.   What are the AF, Normal, and Interference Detectors?

Kardia 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 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 Kardia’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.


8.   What do I see when AF is detected? What do I do 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 for analysis or sharing it with a medical professional.”  We recommend that you share the recording with a medical professional or send to Kardia’s ECG analysis service for review.


9.   What do I see when my recording has interference? What do I do if it says “Unreadable”?

You will see the message, "Unreadable”. There was too much interference in this recording. Try to relax and hold still, rest your arms, or move to a quiet location." You can then either try again or save the recording.

1.    Per the User Manual, please try the following tips for acquiring the best quality ECG recording:

2.    Ensure that the “Enhanced Filter” is on.

3.    Clean the electrodes on the Mobile ECG with alcohol-based sanitizer.

4.    If hands are very dry, use a water-based lotion before recording.

5.    When recording from the hands, relax the arms and hands to reduce muscle noise. Rest the forearms and hands on a flat surface and let the Mobile ECG rest on the hands. Do not squeeze the Mobile ECG.

6.    Ensure that your smartphone/ tablet is not charging/syncing and you are not using headphones with your smartphone or tablet during the recording.

7.    Make sure that both the smartphone/tablet and you remain still during ECG recordings. Movement during recordings will cause noise in the tracing.

8.    Make sure Mains Filter is set appropriately for your geographical location. This can be adjusted under the Kardia app Settings.

9.    Try recording from the chest, right under the pectoral muscle in the mid line.


10. 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.
