New Atrial Fibrillation

Walter Thompson is a 71-year-old male presenting with i was recently told i have atrial fibrillation and need to discuss treatment options. I went to my doctor for a routine checkup last week and they did an EKG that showed I have atrial fibrillation. Honestly, I don't have any symptoms - no palpitations, no shortness of breath, no chest pain. I feel fine. Your task is to take a focused history from this patient.
