Michael, good morning I hope you are well and having a great Thursday. With regard to your question, consider the following. EKG and ECG are one in the same. An electrocardiogram which is abbreviated ECG is taken from the German word Elektrokardiogramm which you can see would be abbreviated EKG. EKG or ECG is a noninvasive transthoracic graphic produced by an electrocardiograph, which records the electrical activity of the heart over time.
We hope this helps. Take care and have a great Thursday.
