What is electrocardiogram

The electrocardiogram represents the graphical recording of the potential variations

that arise during cardiac activity.

An electrocardiogram provides information about:

• Heart rate

• The origin of the impulse and its propagation (conduction) through the mass of the myocardium

• The size of the heart cavities

• Heart position

• Extension and localization of an acute myocardial infarction (AMI)

• The effects of changing the concentration of electrolytes on the properties of the myocardium

• The effects of some drugs on the activity of the heart

• Operation of an artificial pacemaker implanted in a patient

• Represents the "gold standard" for the diagnosis of arrhythmias
