Which term is the machine that records the heart's electrical pattern?

• A. Electrocardiograph
• B. Electrocardiogram
• C. Endarterectomy
• D. Efferent

Answer: (A)

The device that records the heart’s electrical activity is the electrocardiograph. It functions as the instrument, taking the electrical signals from the heart and turning them into a readable trace. The resulting graph is called an electrocardiogram, which is the record produced by the machine. Endarterectomy is a surgical procedure to remove plaque from an artery, and efferent describes nerve signals traveling away from a nervous system structure—these are unrelated to the device, which is why electrocardiograph is the correct term.
