Before You Buy Kardia

Is Kardia FDA cleared/CE marked?

Yes. Kardia is FDA cleared and CE marked. Kardia is intended to record, store and transfer single-channel electrocardiogram (ECG) rhythms. Kardia also displays ECG rhythms and detects the presence of atrial fibrillation and normal sinus rhythm when prescribed or used under the care of a physician. Kardia is intended for use by healthcare professionals, individuals with known or suspected heart conditions and health conscious individuals. It is cleared for individual use and for those weighing at least 10kg (22 lbs). The device has not been tested for and is not intended for pediatric use.

Will Kardia work on my smartphone or tablet?

Kardia is compatible with many popular smartphones and tablets. Since Kardia Mobile is a medical device regulated by the FDA, rigorous testing must be completed before we can claim compatibility. Click here for a list of our compatible devices.

Do I need phone service or Wi-Fi to take an EKG recording on my Kardia Mobile?

Once logged in, the Mobile ECG does not require a Wi-Fi or mobile connection to record an EKG and save it to the phone/tablet, however it requires one of these to: sync automatically with the AliveCor server, email, or print directly from the Kardia app. If you do not have a Wi-Fi or mobile connection at the time of the ECG recording, you can email or print the data later when you have such a connection and the sync will happen automatically at that time.

Do I have to use the attachment plate?

While we recommend that you attach your Kardia Mobile to your device for convenience, it is not required. As long as you are within 12 inches of your smartphone or tablet when using Kardia Mobile to take an ECG recording.

I have a pacemaker or ICD. Can I still use Kardia Mobile?

Kardia Mobile has not been tested for accuracy with ECG recordings taken from users with pacemakers. We cannot recommend Kardia Mobile for users with pacemakers or ICDs because we cannot guarantee the accuracy of the resulting EKG readings.

Is Kardia Mobile covered by my health insurance?

Kardia Mobile is not currently covered by insurance. However, it is eligible for payment using a Flexible Spending Account (FSA), Health Savings Account (HSA) or Health Reimbursement Account (HRA).

Instant ECG Analysis

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.

I keep getting a “noisy” or “unreadable” recording. What does that mean and how can I prevent it?

There are a few reasons why you may be getting noisy or unreadable recordings. Since Kardia Mobile communicates with your smart phone via high frequency ultrasound, it is important that you keep the device within a few inches of the microphone and eliminate any sources of electric interference. Here are some of the common things to look for:

  1. Confirm your smart phone or tablet is not plugged in or charging while recording an EKG
  2. Move away from sources of electrical interference such as large computer monitors or television screens
  3. Be sure you don’t have headphones plugged in to your smart phone
  4. If you wear hearing aids, be sure to turn them off
  5. If your fingers are dry, try moistening them a bit to improve conductivity with the electrodes
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 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.

Privacy & Security

Is AliveCor HIPAA (Health Insurance Portability and Accountability Act) compliant? What does that mean?

Yes, AliveCor is HIPAA compliant. We take the privacy and security of your medical information seriously. This means we follow HIPAA and HITECH regulations as set forth by U.S. Health and Human Services that require Administrative, Physical, and Technical controls to be in place. We comply with HIPAA requirements to use industry best standards to protect and secure your Protected Health Information collected through our Kardia app.

What information do you collect?

When you create a new account, AliveCor collects the following required information: name, email, date of birth, sex, smoking status, height, weight. We use this information to ensure that only you have access to this account. Other information we collect when you create a new account are: activity level, medications and medical conditions. This information is good to have as a baseline to understand your current condition. This information is not required to access your account. If you are a Premium subscriber, we may collect other information you may input into Kardia, such as EKG recordings, blood pressure, resting heart rate and activity levels. If you are a connected patient to your physician, all of this information will be seen in your doctor’s Kardia Pro account for identification and to help your doctor manage your treatment.

Do any third party vendors have access to user information?

External contractors and companies that provide necessary services may have access to some of your information. The vendor which handles payment processing, is a good example of this. Such vendors are required by law to protect the information we share with them. They do not have access to any of your Kardia recordings or health history.

If I’m connected to my physician, who’s responsible for protecting my data?

Leapvault protects the information collected through Kardia and your healthcare provider is responsible for protecting your information as a policy of their practice.

What type of security do you use?

Our adherence to HIPAA means that all data on our servers is encrypted when it is at rest or in transit. AliveCor uses industry best practices such as AES 256-bit server side encryption for customer ECG recordings, and transport layer security (TLS 1.2) to establish a secure link with cloud servers and to encrypt data in transit.

Do you sell my data?

Leapvault does not resell any data we receive. Leapvault may use de-identified ECG recordings for future clinical research and feature improvements. All personal information is removed from a user’s ECG and stored on our secure and encrypted servers.

Does Leapvault collect info of users who may be children?

Kardia is not FDA indicated for pediatric use. We do not knowingly collect personal info from children under 13.
