Detailed explanation-1: -The way that these signals spread through the heart can also be measured on the surface of our skin. An ECG measures these changes in electrical signals (or, in fact, voltage) on different areas of skin and plots them as a graph. The resulting ECG graph is called an electrocardiogram.
Detailed explanation-2: -Both refer to the same procedure, however one is in English (electrocardiogram – ECG) and the other is based on the German spelling (elektrokardiogramm – EKG). It is common to use the German “EKG” in the United States because “ECG” sounds very similar to a different procedure called an EEG.
Detailed explanation-3: -It is an electrogram of the heart which is a graph of voltage versus time of the electrical activity of the heart using electrodes placed on the skin.
