The ability of the ECG application to accurately detect AFib and sinus rhythm in ECG recordings has been validated in a clinical study involving approximately 590 subjects. ECG application heart rate classification is compared to single-lead multi- channel ECG heart rate classification performed by a board-certified cardiologist. Among the classifiable records, the ECG application was able to correctly identify AFib 99.5% of the time and sinus rhythm (SR) 100% of the time.

• In the study, the ECG app determined 11.5 percent of records were inconclusive, including those deemed too poor quality to analyze. When these inconclusive records were included, the ECG application returned AFib results 86.5% of the time for AFib subjects and SR results 91.1% of the time for sinus rhythm subjects. Real- world performance can have higher uncertainty and poorer recorded results.
• The accuracy of the ECG application PDF report was assessed by comparing it with a standard lead I ECG recorded at the same time. Key features of the ECG waveform, such as PR and RR intervals, QRS duration, position and amplitude, and the presence and amplitude of P waves, were compared and found to be statistically equivalent within an acceptable margin of error. A comparison of simultaneous single-lead multichannel electrocardiograms and board-certified cardiologist heart rate classifications recorded by the ECG application had 96% agreement. No adverse events were observed during the clinical study.

After you complete an ECG recording, you will see one of the following results in the ECG app.

SINUS RHYTHM

A sinus rhythm result means your heartbeat pattern appears normal. It indicates that the upper and lower chambers of your heart are beating in sync.

Note: A sinus rhythm result only applies to that specific recording and DOES NOT mean your heart always beats normally.

ATRIAL FIBRILLATION (AFIB)

An AFib rhythm result means your heartbeat pattern appears irregular. AFib is an irregular heart rhythm caused by your heart's upper and lower chambers not beating in sync. You should speak with your doctor if you receive an AFib rhythm result.

Left untreated, AFib can lead to serious health consequences. The irregular heart rhythm causes improper blood flow in the heart, which can lead to stroke, heart failure and/or other medical problems.

AFib can be temporary or persistent, but it is a manageable condition when treated by a doctor and with medication. Many people with AFib live healthy lives. Sometimes people with AFib do not have symptoms. However, others may experience one or more of these common symptoms:

HEART RATE TOO HIGH OR TOO LOW

If your heart rate is over 120 beats per minute (bpm) or under 50 bpm, the ECG app cannot check for AFib heart rhythms. In these cases, the result will be inconclusive, and your heart rhythm could not be classified. If you get this result repeatedly or you do not feel well, then you should speak with your doctor.

A heart rate below 50 bpm can be caused by taking some medications or by certain heart conditions. Some people with high fitness levels may also have a heart rate below 50 bpm.

A heart rate above 120 bpm is common while exercising and for a short time afterward. It can also be caused by high stress levels, an infection, dehydration, alcohol use or certain heart conditions, including AFib.

INCONCLUSIVE

An inconclusive result means your heart rhythm could not be classified. This could happen for several reasons, such as moving too much or poor skin contact during the ECG recording. Try resting your arm on a table, and make sure the watch is snug on your wrist. If you get this result repeatedly or if you do not feel well, then you should speak with your doctor.
