Guide To Atrial Fibrillation Symptoms

Atrial fibrillation is a cardiac condition in which the atria (the upper chambers of the heart) beat rapidly and irregularly. Patients with this condition are at an increased risk of strokes, blood clots, and heart failure. High blood pressure, sleep apnea, lung disease, metabolic syndrome, and diabetes can elevate a patient's chances of developing atrial fibrillation, and obese individuals are at a higher risk too. Some patients may have episodes of atrial fibrillation that occur intermittently. For others, the condition could persist for months, and some individuals have permanent atrial fibrillation. To diagnose this condition, doctors start by listening to the patient's heart with a stethoscope. This helps doctors understand whether the rhythm of the patient's heart is normal. Based on information from the physical exam, the doctor might decide to order further tests. An electrocardiogram is the primary tool used in the diagnosis of atrial fibrillation, and doctors might also recommend an echocardiogram, Holter monitor, event recorder, or stress test. Treatment options for this condition include electrical cardioversion, cardioversion with medication, and catheter ablation. Many patients also take medications such as dofetilide and amiodarone to help the heart maintain a regular rhythm and prevent future episodes.
