What is one of the first line treatments for symptomatic atrial fibrillation?

One of the first-line treatments for symptomatic atrial fibrillation is beta-blockers. These medications work by slowing down the heart rate and helping to control the speed of the electrical signals that pass through the heart. By reducing the heart rate, beta-blockers can alleviate symptoms often associated with atrial fibrillation, such as palpitations, shortness of breath, and fatigue. They also provide an essential therapeutic benefit in managing the overall rhythm of the heart.

In contrast, antidepressants, antihistamines, and statins do not directly address the management of atrial fibrillation or its symptoms. Antidepressants are primarily used for mood disorders, antihistamines are used to treat allergic reactions, and statins are primarily prescribed to manage cholesterol levels. Therefore, they are not indicated for the treatment of atrial fibrillation.
