How do you manage asymptomatic non-sustained atrial arrhythmia in patients with single ventricle and Fontan physiology?

This is an excellent, challenging question and I think experts will disagree and debate the issue depending if they are risk-minimizers or cost-minimizers and if patients are worriers (woulda, coulda, shoulda) or data-driven/evidence-based (need to see large studies with proof before action).
