The electrical activity of your heart is measured by a common, non-invasive test called an electrocardiogram, or ECG. It is helpful in determining the general health of the heart, diagnosing irregular heart rhythms, and looking for evidence of previous heart attacks. To learn more about how your heart works, your doctor may suggest this test if you experience symptoms like palpitations, dizziness, shortness of breath, or chest pain. Electrodes are tiny stickers that are applied to your arms, legs, and chest during the procedure. These electrodes are connected to a device that records electrical impulses from the heart and prints them as a graph. The test is completely painless and typically takes five to ten minutes. Wearing loose clothing can make the electrodes stick more comfortably, but there is no special preparation required. Since the test is non-invasive and doesn’t involve radiation or electricity, there is no risk. You can immediately get back to your regular activities after the test. In order to help you determine whether there are any problems that require attention, Dr. Ahuja goes over the results and explains their significance. Because of this, the ECG is a helpful starting point for assessing heart health.
