Electrocardiogram (ECG) is a graphical representation of the electrical activity of the heart.

An ECG machine records the electrical signals generated by the heart as it beats.

ECGs are used to diagnose various heart conditions, such as arrhythmias, myocardial infarction (heart attack), and heart failure by analyzing the patterns of electrical waves. It does not measure activity of the cornea, kidney, or brain (which is typically measured by EEG).
