What are potential other workups that may need to be done?

Patients with Atrial fibrillation may be at increased risk for death and heart failure and therefore an echocardiogram, or ultrasound of your heart, and a stress test may need to be completed.

There are also patients who have sleep apnea, or a disorder of sleeping, and a clear association with atrial fibrillation. To fully evaluate this a sleep study may need to be performed.
