Feel your heartbeat. Is it fast? This is normal if you\u2019ve been exercising, or if you\u2019re worried or scared. But sometimes a fast heartbeat can be a sign of atrial fibrillation, or AFib, a common condition that is important to treat. If left untreated, this heart condition can lead to a stroke. Fortunately, AFib is highly treatable, and your doctor can advise you on how to manage your condition and help you to lead an otherwise normal, healthy life. So, what should you know about AFib?\nFind out if you\u2019re at risk or if the warning signs and symptoms apply to you.\nWhat Is Atrial fibrillation (AFib)?\nYour heart has an electrical system that keeps the top chambers (the atria) beating in time with the bottom chambers (the ventricles). When the electrical signals are normal, you have a normal, steady heartbeat.\nAFib happens when the electrical system sends out uneven signals that make the atria quiver, or fibrillate, instead of beating normally. This throws off the heart\u2019s rhythm and can cause a fast or irregular heartbeat. Other symptoms can include:\n\nFluttering in the chest, also called palpitations\nChest discomfort\nDizziness or light-headedness\nShortness of breath\nWeakness\nFatigue, or feeling very tired\n\nWho gets AFib?\nMillions of people in the United States have AFib, and common risk factors include:\n\nAge. It is very common in people 60 and older, and the older you get, the more you are at risk.\nLifestyle. What you eat, how active you are, if you\u00a0smoke, if you drink heavily, how you sleep, and how you manage stress all play a part.\nHealth conditions.\u00a0High blood pressure, diabetes, obesity, and other heart problems can raise your risk.\n\nIs AFib Dangerous?\nIf you have symptoms of AFib, talk to your doctor right away. While it\u2019s unusual for AFib to be life-threatening on its own, it can lead to very serious, even deadly, conditions like stroke. People with AFib have a higher risk of stroke because their hearts don\u2019t pump blood properly. This can make blood pool or clot, and if a clot moves from your heart to your brain, a stroke can happen.\nPeople with AFib are also more likely to develop other heart problems, or obesity. It\u2019s important to understand your risks and to talk with your doctor about how to lower them.\nHow Is AFib Treated?\nYour doctor will suggest a treatment plan that fits your needs. This may include:\n\nChanges to your lifestyle. A\u00a0heart-healthy diet, regular exercise, quitting smoking, lowering your alcohol intake, and finding ways to handle stress are important.\nMedicines. Your doctor might have you take medicines that lower your risk of blood clots, that help your heart beat slower, or that get your heart back to a normal rhythm.\nDevices. Some people need pacemakers and defibrillators, which are small devices that are placed inside your body and help control your heart beat.\nSurgery or other medical procedures. There are surgeries and other medical procedures that can treat AFib, and your doctor will let you know if one is right for you.\n\nRemember, if you think you have AFib, it\u2019s important to talk to your doctor right away. The sooner you\u2019re diagnosed, the sooner you can get treatment and begin lowering your risk of stroke.\nVisit the UPMC Center for Atrial Fibrillation online or call 1-844-HVI-AFIB (484-2342) to schedule an appointment or learn more.
