Symptoms of atrial fibrillation include heart palpitations, chest pain and breathing difficulties, explains Mayo Clinic. Individuals with atrial fibrillation may also feel weak or fatigued. In certain cases, the condition causes no symptoms.
Additional symptoms of atrial fibrillation include a fluttering sensation in the chest, anxiety and sweating, according to the American Heart Association. Chest pain and pressure may also indicate atrial fibrillation. These symptoms can also signify a heart attack, so it is imperative to seek medical attention in the event of any type of chest discomfort. Nonsurgical treatment options for atrial fibrillation include electrical shock procedures and catheter insertion procedures that restore balanced heart rhythms.
