If you are middle-aged or elderly and have risk factors for a heart attack -- such as high blood pressure, high low-density lipoprotein (LDL) cholesterol, or diabetes -- you should probably have an electrocardiogram (ECG) yearly, even if you're feeling fine. Also, because there are wide ranges of what's considered a "normal" ECG, it's helpful to have a baseline ECG to compare against future tests, to spot any abnormal changes.

Heart and Circulatory System

Your circulatory system is made up of your heart and three main types of blood vessels -- arteries, veins and capillaries. Your heart is at the center of the system, acting as a pump to distribute nutrient- and oxygen-rich blood through your body; it then takes away carbon dioxide and other waste your body doesn't need. Signs of poor circulation include cold hands and feet, numbness, dizziness, migraines, varicose veins and pain in your feet or legs. Untreated, poor circulation can lead to stroke, high blood pressure, kidney damage and other diseases. Learn more about your heart and circulatory system with expert advice from Sharecare.
