any insights on why leads fail?
My husband just had his 3d pacemaker surgery plus ablation in a year. 2 lead biotronik was placed in July. One lead failed in late July and was replaced. Then he began having lightheadedness early this year. We switched EPs. Turns out he was having atrial flutter plus a failed lead. So he had ablation and now yesterday a lead revision. Could it just be bad luck on the leads or what else could be going on? Thanks for any insights!
