5. Unreadable EKG results determines that you didn’t have proper EKG recording for analysis. You may try to re-record your EKG.

Indications For Use

The KardiaMobile 6L System is intended to record, store and transfer one- and two-channel electrocardiogram (EKG) rhythms. In single channel mode, the KardiaMobile 6L System can record Lead-I. In two channel mode, the KardiaMobile 6L System can record Lead-I and Lead-II simultaneously and derive Lead-III and unipolar limb leads aVR, aVF and aVL. The KardiaMobile 6L System also displays EKG rhythms and output of EKG analysis from AliveCor’s KardiaAI platform including detecting the presence of normal sinus rhythm, atrial fibrillation, bradycardia, tachycardia, and others. The KardiaMobile 6L 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 use.

Features & Functionality

KardiaMobile 6L is a 3-electrode personal EKG device that is capable of recording two kinds of EKGs: a Single-Lead EKG and a Six-Lead EKG, which provides more data for you to share with your doctor. Both EKG types detect normal sinus rhythm, atrial fibrillation, bradycardia, tachycardia, and indeterminate results (errors or unclassified rhythms).
KardiaMobile 6L has two electrodes on the top surface and one on the bottom surface. It is powered by a replaceable battery, which is located under the bottom electrode. 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, 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.

Six-Lead EKG

A Six-Lead EKG uses three electrodes to provide information about your heart rhythm from six different viewpoints. It is done by resting the bottom electrode on the bare skin of your left leg (knee or inside of the ankle), and placing fingers from your left and right hand on the top two electrodes. This is comparable to Leads I, II, III, aVF, aVL, and aVR on standard EKG machines used in the hospital or doctor’s office.

Healthcare Professional Review (Rx Only)

Health care professionals (HCPs) may review and analyze the recorded EKG. The Kardia app provides users with the ability to forward the recorded EKG to their HCP in one of two ways, one by using a referral code with HCPs who use Kardia Pro, and the other, by emailing the EKG PDF to the HCP. When connected to Kardia Pro, the user’s EKG recordings are automatically transferred and made available to the HCP. HCPs can review the EKG PDF to perform rhythm assessments as well as measure the QT interval.
Note: An EKG from the KardiaMobile 6L is recorded in a sitting position (unlike a diagnostic that is recorded supine) leading to positional effects on the QT interval; this effect may be mitigated with the use of the heart-rate corrected QT interval. A summary of the clinical validation to demonstrate the accuracy of measuring the heart-rate corrected QT interval (QTc) using KardiaMobile 6L is provided in the section titled “Clinical Safety and Performance”.
WARNING: Manual EKG analysis is only intended for trained HCPs and lay untrained users should not analyze an EKG nor make any diagnostic assessments.

EKG Instant Analysis

Upon completion of your EKG recording, KardiaMobile 6L transmits the EKG data to the Kardia mobile app. The EKG is then processed by AliveCor’s Instant Analysis algorithms. The app will display your full Single-Lead or Six-Lead EKG and the Instant Analysis result with description.
Representative Instant Analysis results, descriptions, and additional information are displayed in the table below. Note that Instant Analysis noted as “Advanced Determinations” will be provided only if you have access to them, such as through a KardiaCare membership.

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.

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 quality of the KardiaMobile 6L System for recording a 6-lead EKG was validated in a clinical study. Overall, 44 subjects participated in the study, comprising nearly equal numbers of healthy volunteers and arrhythmia patients. EKG recordings were simultaneously taken by the KardiaMobile 6L and a standard clinical-grade 12-lead EKG device. Qualitative and quantitative analyses of equivalence were performed on the 44 pairs of EKG results.
For qualitative assessment, two board-certified electrophysiologists compared 6-lead EKG rhythm strips acquired from the KardiaMobile 6L device and the corresponding leads from the reference standard 12-lead EKG device for diagnostic equivalence. All paired recordings (100%, n=44 subjects), were deemed equivalent for assessing cardiac arrhythmias by both electrophysiologists. The results of the assessment determined that the subject device records a 6-lead EKG that is qualitatively equivalent to the recordings of corresponding leads from a gold standard 12-lead EKG device.
For quantitative equivalence, median beat cross correlation for Lead I and II and RMS error for all 6 limb leads were computed between the paired EKGs for each subject. This analysis was conducted on the unfiltered EKG output as well as the enhanced filtered (EF) EKG output. KardiaMobile 6L EKGs had a minimum correlation of 0.96 and a maximum RMS error of 47 μV as compared to the corresponding lead of the 12-lead EKG. The results of the quantitative analysis of the EKG recordings further confirmed that the KardiaMobile 6L device EKG has equivalent output to that of the gold standard 12-lead EKG device.
During this clinical study, no adverse events were observed.
Additionally, in a separate study, the accuracy of measuring the heart-rate corrected QT interval (QTc) using KardiaMobile 6L was clinically validated. In this study, EKGs were concurrently recorded using KardiaMobile 6L and a 12-lead diagnostic EKG device from 313 patients. An independent core lab measured the QT and RR intervals using the procedure used in Thorough QT studies, as described below:

• Interval duration measurements were made on a single lead. With the 6-lead EKGs, the intervals were measured on lead II after applying AliveCor’s Enhanced Filter. When Lead II was not analyzable, the secondary measurement lead was Lead I, and the tertiary measurement lead was Lead III. In the case of the 12-lead, the interval duration measurements were performed on Lead II without filtering. When the 12-lead’s Lead-II was not analyzable, the secondary measurement lead was V5, and the tertiary measurement lead was V2.
• QT interval measurements were performed on the first 3 beats and the average of the three was used as the QT for the EKG.
• The heart-rate corrected QT was computed using both the Bazett’s and Fridericia’s formulas. For each of the three beats used to measure the QT, the RR-interval to the subsequent beat was measured and the beat’s QT was corrected using the appropriate formula. The average of the three beat’s heart-rate corrected QT was used as the final measured QTc.

The results of the quantitative analysis confirmed that the QTc measured from EKG recorded using KardiaMobile 6L in a sitting position was equivalent to that measured from a gold standard diagnostic 12-lead EKG device recorded in a supine position. During this clinical study, no adverse events were observed.
