What does ECG stand for?

• A. Electroencephalogram
• B. Echocardiogram
• C. Electromyography
• D. Electrocardiogram

Answer: (D)

ECG stands for electrocardiogram. It records the heart’s electrical signals using surface skin electrodes, capturing how the electrical impulses coordinate the heartbeat. This helps evaluate heart rate, rhythm, and conduction, and can reveal issues like arrhythmias or ischemia. Other terms refer to different things: electroencephalogram measures brain electrical activity, electromyography measures muscle electrical activity, and echocardiogram uses ultrasound to visualize heart structure and function. ECG is specific to the heart’s electrical activity, which is why it’s the correct term.
