Brief summary
AliveCor (www.alivecor.com) has developed an ECG device (KardiaMobile) that interfaces with iOS and Android smartphones and tablets. This ECG consists of a lightweight hardware case with two metal electrodes that can snap onto the back of the phone and a software application. By holding the right finger(s) on the right electrode and the left finger(s) on the left electrode, an electrical circuit is completed and a lead-I, 30 second rhythm strip is created. KardiaMobile and a newer device, KardiaMobile 6L, were approved by FDA for ECG rhythm recording. Recently, AliveCor developed two new devices: Kardia 12L and Kardia 6L to record 12- lead and 6-lead ECGs, respectively. However, the data generated from the two new devices have not yet been validated for accuracy. The purpose of this study is to evaluate the accuracy of the ECGs recorded by AliveCor Kardia 12L and 6L devices. This will be compared to simultaneous standard of-care 12-lead ECG recordings. The ECGs will be analyzed for accuracy and statistical difference using root-mean-square error and cross correlation between the median beats.
Interventions
DEVICEKardia 12L
The purpose of this study is to collect clinical validation data to support an FDA submission for a 510(k) for the Kardia 12L hardware which enables the simultaneous diagnostic quality recording of all 6 limb leads and any chest lead. We will be recording both Leads V2 and V4 in a sequential fashion along with the Limb leads and a simultaneous 12-lead ECG to validate the hardware and a Deep Neural Network model which expands the 7 leads into a complete 12-lead ECG. The 12-lead ECG used for validation of the recordings and the 12-lead synthesis model is the GE Cardiosoft System which is FDA cleared.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Agreement on QRS width between Kardia 12L and ECG | 30 seconds | Quantitative analysis on QRS width will be performed on the median-beat ECGs derived from the recorded ECGs from both devices as well as 12-lead ECG for each study participant |
| Agreement on PR interval between Kardia 12L and ECG | 30 seconds | Quantitative analysis on PR interval will be performed on the median-beat ECGs derived from the recorded ECGs from both devices as well as 12-lead ECG for each study participant |
| Agreement on QT interval between Kardia 12L and ECG | 30 seconds | Quantitative analysis on QT interval will be performed on the median-beat ECGs derived from the recorded ECGs from both devices as well as 12-lead ECG for each study participant |
