Cautions

1. Detection of possible Atrial Fibrillation (AF) in your EKG results are not to be used for
diagnosis. If you are experiencing any concerning symptoms, contact your physician.

2. Result of "Bradycardia" or "Tachycardia" are designations of heart rate, not a clinical
diagnosis of an arrhythmia. Please consult with your physician should you receive
consistent identifications of "Bradycardia" or "Tachycardia".

3. “Unreadable” EKG results determines that you didn't have proper EKG recording for
analysis. You may try to re-record your EKG.

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® (Model AC-019) 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.

Terms

ECG: Also known as an electrocardiogram, an ECG is a test that detects and records the
strength and timing of the electrical activity in your heart. This information is recorded on a
graph that shows each phase of the electrical signal as it travels through your heart.

Single-Lead ECG: When the 2 top electrodes (Left Hand Electrode and Right Hand Electrode)
are used, the Kardia app will display a Single-Lead ECG that is comparable to Lead I on
standard ECG machines.

Six-Lead ECG: When all 3 electrodes (Left Hand Electrode, Right Hand Electrode, and Left Leg
Electrode) are used, the Kardia app will display a Six-lead ECG that is comparable to Leads I, II,
III, aVF, aVL, and aVR on standard ECG machines. It is recommended that you record a Six­Lead ECG (which provides more data to your cardiologist) when possible.

arms, or move to a quiet
location with less
interference.

Heart Rate

Current heart rate is displayed during an ECG recording and the average heart rate is displayed
in completed ECG recordings along with the ECG Analysis.

The Kardia App has an internal QRS detector that is used to measure the heart rate, defined as
the inverse of the R-R time interval. During an ECG recording, the current heart rate is measured
from an average of this inverse calculation over the last 5 seconds.

For stored ECGs, the average heart rate is the average of this inverse calculation over the entire
30 seconds of the recording.

Previously Recorded ECGs

From the Kardia app home screen, tap History to access previously recorded ECGs.

Clinical Testing

The KardiaMobile® (Model AC-019) System was thoroughly evaluated in a clinical study to
ensure users can get a medical grade ECG. Overall, 44 subjects participated in the study, that
included patients with arrhythmias as well as normal subjects. The study showed that the
KardiaMobile® (Model AC-019) device records a 6-lead ECG equivalent to the same leads on a
standard FDA-cleared hospital 12-lead ECG device but at an ambulatory bandwidth. Clinical
equivalence was shown qualitatively, through a review by two Board Certified Cardiac
Electrophysiologists and quantitatively, through a statistical test of equivalence between the two
sets of ECGs assessing various variables.
