What It Says About Your Heart It takes years of training to understand the nuances of an electrocardiogram (EKG), but understanding the basics can help you be a better-informed member of your care team. A Northwestern Medicine cardiologist explains what you need to know about an EKG. Basics of the Heart Your heart has four main chambers: a right and left atrium, and a right and left ventricle. The right side of your heart, which includes your right atrium and right ventricle, takes in blood that is depleted of oxygen and pumps it to your lungs. The left atrium then receives the oxygen-rich blood from your lungs and, with the help of your left ventricle, pumps this blood throughout your body to deliver oxygen to your cells. As your blood moves through your body, your cells remove its oxygen. Oxygen-poor blood then returns to the right side of your heart, which sends it back to the lungs, and the cycle continues. Your heart does this roughly 100,000 times a day, pumping around 2,000 gallons of blood. What Does Your Heart Look Like? How an EKG Works An EKG measures electrical activity of the heartbeat, which is your body’s way of moving blood. Heartbeats are created by an electrical impulse that causes the heart to contract, or squeeze. This pushes blood through the chambers. The EKG translates the heart’s electrical activity into visible waves. The size and relationship between waves can tell your physician if the electrical signal is being conducted normally or if there are...
