You are correct! You are incorrect!
A tell-tale symptom of atrial fibrillation is:
The most recognizable sign of atrial fibrillation is heart palpitations, where your heart beats so fast that you think it is racing and/or you can feel it thumping or flopping in your chest. It may be accompanied by chest pain, lightheadedness or dizziness, weakness, or shortness of breath.
True or False: The main risk associated with untreated atrial fibrillation is stroke.
If a clot forms in the left atrial chamber — on the left side of the atrial chamber — it can break off and travel to other parts of the body including the brain. About 15 percent of all strokes occur as a result of atrial fibrillation.
True or False: The only way to manage atrial fibrillation is through invasive surgery.
False. Many people are able to control their atrial fibrillation through drugs. To slow heart rate, doctors usually rely on beta-blockers, and antiarrhythmic medications are used to suppress arrhythmias or to convert an arrhythmia to a normal rhythm. If medications don't work, your doctor may suggest looking to alternatives, like electrical cardioversion, catheter ablation, or a procedure called Maze, which requires open heart surgery.
What happens to the heart during atrial fibrillation?
Atrial fibrillation occurs when rapid, disorganized electrical signals cause the heart's two upper chambers to contract rapidly and irregularly.
True or False: Stress can cause atrial fibrillation.
True. Atrial fibrillation can also happen to otherwise healthy people, especially when they are stressed or fatigued, have had too much caffeine or alcohol, have smoked, or have exercised too much.
Risk factors for atrial fibrillation include:
True or False: The outlook for people diagnosed with atrial fibrillation is grim.
People who have atrial fibrillation can live normal, active lives. For some people, treatment can restore normal heart rhythms. For people who have permanent atrial fibrillation, treatment can help control symptoms and prevent complications. Treatment may include medicines, medical procedures, and lifestyle changes.
Within which age group is atrial fibrillation most prevalent?
While atrial fibrillation is seen in only about 1 percent of the total U.S. adult population, it affects about 3.8 percent of those older than 60 years and 9.0 percent of those older than 80 years.
