Which cardiac assessment test records the electrical activity of the heart?

• A. Stress test
• B. RE E
• C. DEXA
• D. EKG

Answer: (D)

The test that records the electrical activity of the heart is the electrocardiogram, often called an EKG. The heart’s rhythm and the timing of its beats are governed by electrical impulses. By placing small sensors (electrodes) on the chest and limbs, an EKG picks up these signals and creates a tracing that shows heart rate, rhythm, and the way impulses travel through the heart. This direct measurement of electrical activity is exactly what the test is designed to capture, making it the best choice here. A stress test looks at how the heart performs under physical stress and may include monitoring, but its primary purpose is functional assessment during exercise rather than simply recording electrical signals. A DEXA scan measures bone mineral density. The remaining option isn’t a standard cardiac test and doesn’t assess the heart’s electrical activity.
