To begin recording an ECG session, open the Qardio App and place the QardioCore around your chest. 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 this article on wearing and fitting QardioCore to learn how to put on QardioCore for an accurate measurement.
The ECG recording can be stopped at any time by detaching the left clip from QardioCore and removing it from the chest.
