What are the effects of atrial fibrillation?

1 doctor answer
Dr. Martin Bress
49 years experience in Internal Medicine
See below.: The most important effect of atrial fibrillation is the risk of clots arising in the atrium and causing a stroke when the clot leaves the atrium and lands in the brain. Patients with atrial fib may have decreased exercise tolerance and shortness of breath due exaggerated heart rate response. Patients may have fatigue due to decreased cardiac output. The feeling of palpitations may cause anxiety.
