13.  ECG Analysis 

Subsequent recordings: 

-

 

After an ECG recording is complete, the ECG is analyzed to determine if it is at least 

60 seconds long, if it is no Atrial Fibrillation, Unclassified, if Atrial Fibrillation is present, 

or if it is too noisy to interpret. 

-

 

To view the ECG, please visit the history page. 

-

 

The presence of Atrial Fibrillation (AF) in your ECG results may present only potential 

findings. If you are experiencing any symptoms or have concerns, contact your 

physician. 

-

 

Unreadable ECG results determine that you didn’t have proper ECG recording for 
analysis. You might try to re-record your ECG. 

-

 

ECG reports viewed at any magnification other than 100% may appear distorted and 

could lead to misdiagnosis. 

-

 

All ECGs are synced to the Amazfit Health app. You may use the phone app to send 

your ECGs for physician analysis.
