4. Wiill the measurement be correct Yes ECG can be recorded after exercise During measurement please remain in a stable position to avoid noise interference Can Cardio be used during commuting During commuting if user is able to keep a stable position Cardio can be used to measure ECG Usage of Cardio is not recommended during the operation of any vehicle Can conducting gel or other fluids be used when using Cardio Cardio is designed to be operated without any conducting gel or other fluids Please do not apply any conducting gel or other fluids to avoid damaging the thumb electrodes and the device 39 Cardio GLOSSARY Aorta The main trunk of the systemic arteries carrying blood from the left side of the heart to the arteries of all limbs and organs except the lungs Arrhythmia Irregularity in the force or rhythm of the heart beat Atrioventricular AV Node A small mass of specialized cardiac muscle fibers located in the wall of the right atrium of the heart that receives heartbeat impulses from the sinoatrial node and directs them to the walls of the ventricles Bundle of His A slender bundle of modified cardiac muscle that passes from the atrioventricular node in the right atrium to the right and left ventricles by way of the septum and that maintains the normal sequence of the heartbeat by conducting the wave of excitation from the right atrium to the ventricles called also atrioven
