: The main difference between ECG and EKG is that ECG is a more general term that includes both electrical cardioversion (the use of electricity to "shock" the heart back into a normal rhythm) and electroencephalography (a test to measure the electrical activity of the brain).
EKG, on the other hand, specifically refers to electrocardiography, which is the measurement of electrical activity in the heart. This measurement can be used to detect problems with heart function or rhythm.
