How does it work?
To carry out the test, the healthcare professional connects the wires of the electrocardiogram to the skin of the patient using adhesives or suction cups called "electrodes", which are connected to the ankles, wrists and chest in order to detect electrical impulses from different parts of the body.
During the electrocardiogram, the patient must be lying down, relaxed and silent, with normal breathing and with their arms and legs still. Occasionally, the doctor may ask the patient to hold their breath for a few seconds.
The electrocardiogram records electrical activity from the surface of the heart, thanks to electrodes that are stuck to the body. This record of electrical activity is then copied onto paper that is then interpreted by a professional based on the patient’s symptoms and clinical history.
It is a simple, fast test that causes no discomfort or pain. It poses no risk to patients.
