An arrhythmia is an abnormal heart rhythm. This means that your heart beats too quickly, too slowly or irregularly. A fast heart rate is called tachycardia, a slow heart rate is called bradycardia and extra heartbeats that disrupt your regular heart rhythm are called premature ventricular contractions (PVCs). These different arrhythmia conditions have different causes and need different treatments. Learn more about these three types of arrhythmias, their symptoms, causes and the common diagnostic tests that might help you receive a diagnosis.

Learn about coronary artery disease (CAD), which is caused by a blockage in one or more coronary arteries that supply blood to the heart. The blockage occurs when plaque builds up, over time, inside the coronary arteries. Eventually plaque can narrow your coronary arteries, slowing blood flow to your heart. This decreased blood flow can cause symptoms or a heart attack. Learn more about CAD, its causes, various symptoms you might experience and tests that can help your doctor diagnose CAD.

Heart failure is a serious condition that means your heart does not pump as well as it should. When your heart cannot pump effectively, your body does not receive enough oxygen to function normally. There are different types of heart failure, but it is typically a chronic, long-term condition that worsens over time. Receiving a heart failure diagnosis early can help you manage your heart failure more effectively over time. Learn about the symptoms and causes of heart failure as well as basic information about receiving a heart failure diagnosis.

Peripheral artery disease (PAD) is caused by a blockage in one or more arteries that carry blood to your legs, arms, stomach or head. It usually affects the legs. The blockage occurs when plaque (a waxy substance) builds up inside the arteries. Over time enough plaque can build up and narrow your arteries, slowing blood flow to that part of your body. Learn more about PAD, its causes, various symptoms you might notice, and tests that can help your doctor diagnose PAD.

Learn about heart valve disease, which affects one of the heart’s four valves. Two valves—the mitral valve and tricuspid valve—pump blood from each of the heart’s upper chambers (atria) into its lower chambers (ventricles). The pulmonary valve pumps blood from the right ventricle to the lungs, to give oxygen to the blood. The aortic valve pumps oxygen-rich blood from the left ventricle out to the entire body. Sometimes a valve doesn’t open as well as it should (stenosis). Other times a valve doesn’t close tightly (regurgitation, or a leaky valve). Each condition, for each type of valve, can have different causes and need different treatments. Learn about the types of heart valve disease, their symptoms and causes and some common tests that might help you receive a diagnosis.
