Can atrial fibrillation be caused by anxiety?
We don’t fully know the connections between atrial fibrillation and anxiety. Research has identified Afib as a cause of anxiety (if you have Afib, you might worry about your symptoms or quality of life). But few studies have explored anxiety as a cause of Afib. We do know that anxiety can raise your risk of cardiovascular disease and causes a 48% higher risk of cardiac death. However, we need more research to find out if anxiety disorders can cause Afib.
