question: I have a history of heart disease and have had a few bouts of Afib. Been taking Pradaxa, Sotalol and Isosorb. Had an ablation about a year ago and they stopped the Sotalol. Afib returned and I was put back on Sotalol. Lately, I ve had ongoing PVC s and PAC s for weeks. Was given Magnesium but they continue. Doctor is suggesting another ablation but I m not confident.
