Mark, some A-fib/A-flutter (cardio said I was having both) began a week after my valve replacement. I was put on a temporary regimen of a med called Sotalol (which required brief rehospitalization) and 3 months of Coumadin but they also gave me IVs of magnesium. Mineral balance is evidently important with arrhythmias.
Hope you're feeling better soon and your sleep issues resolve and arrhythmias too .
