The KardiaMobile Card System is intended to record, store and transfer single- channel electrocardiogram (ECG/EKG) rhythms. The KardiaMobile Card System also displays ECG rhythms and output of ECG analysis from AliveCor’s KardiaAI platform including detecting the presence of normal sinus rhythm, atrial fibrillation, bradycardia, tachycardia, and others. The KardiaMobile Card System is intended for use by healthcare professionals, patients with known or suspected heart conditions and health conscious individuals. The device has not been tested and is not intended for pediatric use1.
Features & Functionality
KardiaMobile Card is a personal EKG device that is capable of recording a Single-Lead EKG. It has two electrodes on the top surface and is powered by a non-replaceable battery. Bluetooth is used to wirelessly transmit EKG data from the device to your smartphone or tablet.
What is an EKG?
Also known as an electrocardiogram or ECG, an EKG is a test that detects and
records the strength and timing of the electrical activity in your heart. Each
heartbeat is triggered by an electrical impulse. Your EKG represents the
timing and strength of these impulses as they travel through your heart.
Single-lead EKG
A Single-Lead EKG is the simplest way to record your heart rhythm. It measures
a single view of the heart. It is taken by laying the device on a flat surface
near your smartphone and placing fingers from the left and right hand on the
top two electrodes of the device. This is comparable to Lead I on standard EKG
machines used in the hospital or doctor’s office.
Setting up your KardiaMobile Card device for the first time
-
Remove your KardiaMobile Card device from the packaging.
-
Download the Kardia app from the App Store or Google Play Store.

EKG Analysis
Instant Analysis | Description | Additional information |
---|---|---|
Bradycardia | Your heart rate is less than 50 beats per minute, which is | |
slower than normal for most people. | Kardia does not check for heart attack. |
If you believe you are having a medical emergency, call emergency services. Do
not change your medication without talking to your doctor.
Normal| No rhythm abnormalities detected in your EKG.| Kardia does not
check for heart attack. If you believe you are having a medical emergency,
call emergency services. Do not change your medication without talking to your
doctor.
Tachycardia| Your heart rate is faster than 100 beats per minute. This
can be normal with stress or physical activity.| Kardia does not check for
heart attack. If you believe you are having a medical emergency, call
emergency services. Do not change your medication without talking to your
doctor.
No Analysis| Your EKG recording is of insufficient duration. Instant
Analysis is not able to provide an analysis on EKG recordings shorter than 30
seconds.| Record a new EKG. Try to relax and hold still, rest your arms, or
move to a quiet location that will allow for a full 30 second recording.
Unclassified| Atrial fibrillation was not detected and your EKG does not
fall under the algorithmic classifications of Normal, Bradycardia, or
Tachycardia. This may be caused by other arrhythmias, unusually fast or slow
heart rates, or poor quality recordings.| Kardia does not check for heart
attack. If you believe you are having a medical emergency, call emergency
services. Do not change your medication without talking to your doctor.
Unreadable| There is too much interference in this recording.| Please
re-record the EKG. Try to relax and hold still, rest your arms, or move to a
quiet location or away from electronics and machinery.
Upon completion of your EKG recording the EKG is processed by AliveCor’s
Instant Analysis algorithms in the Kardia app. The app will display your full
EKG and the Instant Analysis result with description.
All possible Instant Analysis results, descriptions, and additional
information are displayed in the table below:
WARNING: After EKG analysis, the app may incorrectly identify ventricular
flutter, ventricular bigeminy, and ventricular trigeminy heart conditions as
unreadable. Please consult with your physician.
NOTE: All historical EKGs and Instant Analysis results can be viewed,
downloaded, and emailed from the “History” section of the Kardia app.
EKG reports viewed at any magnification other than 100% may appear distorted
and could lead to misdiagnosis.
Heart Rate
During your EKG recording, your real-time heart rate will be shown. When
reviewing previous EKGs, the average heart rate taken during that recording is
displayed.
Heart rate is calculated as the time interval between consecutive heart beats;
or more specifically as the inverse of the time interval between consecutive
R-waves in your QRS complex. During an EKG recording, the current heart rate
is measured from an average of this inverse calculation over the last 5
seconds. For stored EKGs, the average heart rate is the average of this
inverse calculation over the entire 30 seconds of the recording.
Clinical Safety and Performance
The KardiaMobile family of devices has been extensively validated in clinical studies at several leading institutions. KardiaMobile and KardiaMobile 6L devices have been favorably compared to Lead I recordings of a standard FDA- cleared 12-lead device. Clinical equivalence of recordings from these Kardia devices and the 12-lead EKG device were also validated by board-certified Cardiac Electrophysiologists. See https://www.alivecor.com/research/ for details.

If the amber light does turn on: -
Make sure Bluetooth is turned on in your smartphone or tablet settings and follow the steps on your screen.
-
If Bluetooth is on, try to un-pair and pair again to your KardiaMobile Card.
-
-
I’m having trouble getting a clear recording.
-
Clean the electrodes using a damp soft cloth. Wash your hands with soap and water. Use a small amount of water to moisten the skin where your fingers make contact with the electrodes.
When recording, relax your arms and hands to reduce muscle noise. Rest the forearms and hands on a flat surface. Do not apply too much pressure to the electrodes. -
Avoid close proximity to items that may cause electrical interference (electronic equipment, computers, chargers, routers, etc.)
-
If you wear hearing aids, turn them off prior to recording.
-
Ensure that your smartphone or tablet is not charging/syncing and you are not using headphones with your smartphone or tablet during the recording.
-
Ensure that the “Enhanced Filter” is on.
-
Make sure Mains Filter is set appropriately for your geographical location. This can be adjusted under the Kardia app Settings
-
-
On my EKG, the recording appears upside down.
- Make sure the device is in the correct orientation with the AliveCor logo and brand name “KardiaMobile” in the top left.
- On the EKG tracing, select the “Invert” option to flip the orientation of the EKG. 4. I see large spikes at the start of my recording
- Large amounts of noise/artifact can be seen for the first few milliseconds of a recording when the Enhanced Filter is looking for your heartbeat. This is very rare and only lasts until your first heartbeat is seen in the app; this doesn’t affect the rest of your recording.

a Field strength from fixed transmitters, such as base stations for radio
(cellular/cordless) telephones and land mobile radios, amateur radio, AM and
FM radio broadcast, and TV broadcast cannot be predicted theoretically with
accuracy. To assess the electromagnetic environment due to fixed RF
transmitters, an electromagnetic site survey should be considered. If the
measured field strength in the location in which KardiaMobile Card is used
exceeds the applicable RF compliance level above, KardiaMobile Card should be
observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as re-orienting or relocating
KardiaMobile Card. b Over the frequency range 150 kHz to 80 MHz, field
strengths should be less than 3 V/m.
