How do we handle dad's new atrial fibrillation diagnosis?

[AriaS]

My dad was just diagnosed with - atrial fibrillation || My dad just got diagnosed with - atrial fibrillation after feeling palpitations for a few weeks. The doctor put him on blood thinners and a beta blocker. He's only in his late 60s and otherwise healthy, so it was a shock. We're all trying to learn about it now. The information is kind of overwhelming, especially about stroke risk and lifestyle changes.
