What does ECG stand for in medical terminology?

The term ECG stands for Electrocardiogram. An Electrocardiogram is a medical test that measures the electrical activity of the heart over a period of time. It provides crucial information about the heart's rhythm, the size and position of the heart chambers, and any issues related to the coronary arteries or heart function. This test is non-invasive, typically involves placing electrodes on the skin, and is vital for diagnosing various cardiovascular conditions, such as arrhythmias, heart attacks, and other heart diseases.

Other terms listed, while related to diagnostic tests, refer to different physiological functions. For example, electromyogram measures electrical activity in muscles, and electroencephalogram assesses brain activity, indicating that ECG specifically targets cardiovascular assessment. Additionally, "endocardial graph" is not a standard medical term and does not correspond to a recognized test in medical practice. Understanding the distinction of these terms is essential for effective interpretation of medical data and communication in clinical settings.
