It is also possible for young people without Afib in their family to develop the disease. Some people with Afib may feel fine and not know they have the condition until it is found in a routine test called an electrocardiogram. Other people have symptoms. The symptoms affect people in different ways. If you are experiencing any of these Afib symptoms, visit your doctor. Paul Dorian talks about symptoms and how they might affect you in this video.
If you are experiencing chest discomfort or other signs of a heart attack , call or your local emergency number immediately. If your pulse is fast and your heartbeat is irregular, your doctor may check you for Afib. They will take your medical history and question you about symptoms and risk factors. Your treatment will be based on your risks, medical profile, needs, preferences and how much symptoms are interfering with your quality of life. There are two general treatment strategies — rate control and rhythm control.
Your doctor will determine which strategy is best for you based on your symptoms and other factors. Here are some tips for managing your medications. Listen to Dr. Paul Dorian and Dr. Jeff Nagge explain blood thinners , INR testing if you are on warfarin and healthy eating while on warfarin in these videos. You can lower your risk of developing other heart diseases and stroke by knowing and controlling your blood pressure, diabetes and blood cholesterol.

Heart disease Conditions A-Z Atrial fibrillation. What is atrial fibrillation? Atrial Fibrillation: Are you at risk of atrial fibrillation? Complications from Afib. Jeff Nagge explains Afib and the link to stroke. Types of Afib Paroxysmal: temporary episodes that come and go. An arrhythmia is when the heart beats too slowly, too fast, or in an irregular way. AFib may happen in brief episodes, or it may be a permanent condition.
Others may experience one or more of the following symptoms:. The risk for AFib increases with age. High blood pressure, the risk for which also increases with advancing age, accounts for about 1 in 5 cases of AFib. When standard stroke risk factors were accounted for, AFib was associated with an approximately fivefold increased risk of ischemic stroke. Strokes caused by complications from AFib tend to be more severe than strokes with other underlying causes.
Strokes happen when blood flow to the brain is blocked by a blood clot or by fatty deposits called plaque in the blood vessel lining. More than , hospitalizations with AFib as the primary diagnosis happen each year in the United States. Certain abnormalities seen on an ECG can also suggest bulges aneurysms that develop in weaker areas of the heart's walls. Aneurysms may result from a heart attack.
If the rhythm is abnormal too fast, too slow, or irregular , the ECG may also indicate where in the heart the abnormal rhythm starts. Such information helps doctors begin to determine the cause. Atrial fibrillation or atrial flutter may occur even when there is no other heart disorder.
More often, these arrhythmias are caused by such conditions as. High blood pressure High Blood Pressure High blood pressure hypertension is persistently high pressure in the arteries.
Often no cause for high blood pressure can be identified, but sometimes it occurs as a result of an underlying Coronary artery disease Overview of Coronary Artery Disease CAD Coronary artery disease is a condition in which the blood supply to the heart muscle is partially or completely blocked.
The heart muscle needs a constant supply of oxygen-rich blood. The coronary Heart valve disorders Overview of Heart Valve Disorders Heart valves regulate the flow of blood through the heart's four chambers—two small, round upper chambers atria and two larger, cone-shaped lower chambers ventricles. Each ventricle has An overactive thyroid gland Hyperthyroidism Hyperthyroidism is overactivity of the thyroid gland that leads to high levels of thyroid hormones and speeding up of vital body functions.
Graves disease is the most common cause of hyperthyroidism A birth defect of the heart Overview of Heart Defects About one in babies is born with a heart defect. Some are severe, but many are not. Defects may involve abnormal formation of the heart's walls or valves or of the blood vessels that enter Heart valve disorders and high blood pressure cause the atria to enlarge, making atrial fibrillation or atrial flutter more likely.
In atrial fibrillation or atrial flutter, the atria do not empty completely into the ventricles with each beat. Over time, some blood inside the atria may stagnate, and blood clots may form. Pieces of the clot may break off, often shortly after atrial fibrillation converts back to normal rhythm—whether spontaneously or because of treatment. These pieces of clot may pass into the left ventricle, travel through the bloodstream becoming emboli , and block a smaller artery.
If pieces of a clot block an artery in the brain, a stroke Overview of Stroke A stroke occurs when an artery to the brain becomes blocked or ruptures, resulting in death of an area of brain tissue due to loss of its blood supply cerebral infarction and symptoms that Rarely, a stroke is the first sign of atrial fibrillation or atrial flutter.
When atrial fibrillation or atrial flutter causes the heart to beat too rapidly, the ventricles do not have enough time to fill completely with blood. Because they do not fill completely, the amount of blood pumped by the heart decreases.
Because blood can pool inside the heart's atria and form clots, atrial fibrillation is a strong risk factor for stroke. Symptoms of atrial fibrillation or atrial flutter depend largely on how fast the ventricles beat.
When the ventricular rate is normal or only slightly increased less than about beats per minute , people usually have no symptoms. Higher rates cause unpleasant awareness of heart beats palpitations Palpitations Palpitations are the awareness of heartbeats.
The sensation may feel like pounding, fluttering, racing, or skipping beats. Other symptoms—for example, chest discomfort or shortness of breath—may In people with atrial fibrillation, the pulse is usually rapid and is always irregular. In people with atrial flutter, the pulse is usually rapid and can be regular or irregular. The reduced pumping ability of the heart may cause weakness, faintness, and shortness of breath. When the ventricular rate is very fast, some people, especially older people and those with heart disorders, develop heart failure or chest pain.
Our study also had several limitations. It is likely that we missed some patients with atrial fibrillation. In patients with asymptomatic atrial fibrillation, which occurs more frequently than what has been previously estimated, 15 , 16 or paroxysmal atrial fibrillation, the only way to detect the arrhythmia would be through frequent repeated electrocardiograms which would depend on atrial fibrillation being present at the time of the test or continuous hour ambulatory electrocardiographic monitoring.
Neither of these options is feasible for such a large population. However, the similarities between our prevalence estimates and those from previous studies suggest that we are not missing a large number of cases.
We were also unable to delineate the prevalence of chronic permanent vs paroxysmal atrial fibrillation. Our US projections were necessarily limited to the assumptions of the underlying census projections 17 and do not adjust for potential future changes in associated conditions such as hypertension and heart failure. Given these caveats, our estimates of the numbers of patients with atrial fibrillation in the future may prove conservative. In conclusion, atrial fibrillation affects 1 in 25 adults 60 years or older and nearly 1 in 10 adults 80 years or older.
Atrial fibrillation confers a large burden from symptoms and ischemic stroke on elderly patients presently, and its impact will be amplified as the number of individuals with atrial fibrillation increases nearly 2. Coordinated efforts by cardiologists, primary care providers, and neurologists will be needed to meet the increasing challenge of stroke prevention and rhythm management in the growing elderly population with atrial fibrillation.
