When you wear a fully charged QardioCore, it will automatically start recording your electrocardiogram after approximately one minute. It is very important that QardioCore is correctly placed. Please read the “Detailed instructions for the correct fitting of QardioCore” and the “Checklist For a Correct and Accurate ECG/EKG Recording” sections on the User Manual with particular care. The ECG recording can be stopped at any time by detaching the left clip from QardioCore and removing it from the chest.
