15  Coala ECG categorization

The Coala Heart Monitor System detects heart rhythm 
deviations based on both the thumb and chest ECG recorded. 
Each recorded measurement, consisting of both chest 
and thumb ECG, is categorized based on any heart rhythm 
deviations detected. 
If no heart rhythm deviations are detected in the recorded 
measurement the measurement will be categorized as 
Category 1 “Your results appear normal”.
For more information on Coala ECG categorization go to 
‘Category description’ under ‘My Coala’ in the Coala App.
