An electrocardiogram (ECG) is a simple test that can be used to check your heart's rhythm and electrical activity.
The overall goal of performing an ECG is to obtain information about the electrical function of the heart.
Medical uses for this information are varied and often need to be combined with knowledge of the structure of the heart and physical examination signs to be interpreted.
The electrocardiogram has no contraindications.
The electrocardiogram has no risks.
The execution of this exam does not include preparation rules.
During an ECG, up to 12 sensors (electrodes) will be attached to your chest and limbs.
The electrodes are sticky patches with wires that connect to a monitor. They record the electrical signals that make your heart beat.
A computer records the information and displays it as waves on a monitor or on paper.
