Question: 1 / 400

Which process involves recording the electrical activity of the myocardium?

Echocardiography

Electromyography

Electrocardiography

The correct answer is electrocardiography. This process is specifically designed to record the electrical activity of the myocardium, which refers to the muscular tissue of the heart. During electrocardiography, electrodes are placed on the skin to detect the electrical signals that result from the heart's rhythm and contractions. It provides vital information about heart function, detects arrhythmias, and can highlight issues such as ischemia or hypertrophy.

In contrast, echocardiography uses ultrasound waves to visualize the heart's structure and function but does not measure electrical activity. Electromyography monitors muscle electrical activity, not specifically related to cardiac tissue, focusing instead on skeletal muscles. Magnetic resonance imaging provides detailed images of organs and tissues in the body but is not intended for recording electrical signals.
