Take the ultimate ECG technician certification exam quiz today if you wish to become one yourself! The electrocardiogram is a noninvasive test that is used to reflect underlying heart conditions. It works by measuring the electrical activity of the heart. Having practiced its use, are you sure you know all there is about how to use it? Take up this test to refresh your memory and learn more. All the best!
