Electrocardiogram, when it must be done

The electrocardiograph is in fact the instrument that is used to perform this, which is equipped with electrodes that, placed on the body (by means of sensors and small suction cups to be placed on the arms, legs and chest) measure the changes that occur during cardiac contraction (systole) and release (diastole).

A person may decide to have an electrocardiogram when he or she performs routine examinations (it is mainly sportsmen who do this periodically).

This is performed when one undergoes a cardiology examination, the examination designed to check the health status of the heart and assess the presence or absence of disorders such as angina pectoris, arrhythmias, myocardial infarction, heart valve disease, heart failure, ischemic heart disease or other disorders affecting the atria and ventricles of the heart.
