There is no difference between an ECG and an EKG. ECG stands for electrocardiogram, and EKG is the German spelling for elektrokardiographie, which is the word electrocardiogram translated into the German language. An ECG (EKG) is a test that measures the electrical activity of the heart. An ECG may also be called a 12-lead ECG or a 12-lead EKG.

Some people prefer to use the abbreviation EKG, even if they speak English because it is less likely to be confused with an EEG (an electroencephalogram), which is a test that measures the electrical activity in the brain.
