Other Information
An electrocardiogram (ECG or EKG) is a recording of the electrical activity of the heart over time produced by an electrocardiograph, usually in a noninvasive recording via skin electrodes. Its name is made of different parts: electro, because it is related to electrical activity, cardio, Greek for heart, gram, a Greek root meaning "to write". In the US, the abbreviation "EKG" , (abbreviated from the German Elektrokardiogramm) is often preferred over "ECG", while "ECG" is used universally in the UK and many other countries. It is preferred as "EKG" in the US because doctor's handwriting of "ECG" can often be confused as "EEG" when transcribing orders or with echocardiography which is also abbreviated "ECG".
