True or False: The ECG records the actual image of the heart.

The ECG, or electrocardiogram, does not record a visual image or representation of the heart itself. Instead, it measures the electrical activity of the heart over time through electrodes placed on the skin. These electrodes detect the depolarization and repolarization of heart muscle cells, which are represented graphically on an ECG strip as waves and intervals. This is a recording of electrical impulses, expressed in a waveform, rather than a direct image of the heart’s structure or its visual activity.

Other options, such as capturing sound waves or video, further highlight the misunderstanding of what an ECG does. Unlike imaging modalities such as echocardiography or MRI, which can provide visual images of the heart’s anatomy and function, the ECG focuses solely on the heart's electrical conduction system. Thus, labeling the statement as false accurately reflects the nature of what an ECG does.
