What does ECG, EKG stand for?

Explanation:
ECG or EKG stands for electrocardiogram, a recording of the heart’s electrical activity over time. This tracing is produced by an electrocardiograph, the device that detects and plots the electrical impulses as the heart beats. Understanding this helps you see why the test is about heart rhythm and conduction, not heart structure. The other terms refer to different things: an echocardiogram uses ultrasound to image the heart, a electroencephalogram records brain activity, and the instrument itself is the electrocardiograph.
