Anyone had a pacemaker at 50? My husband has had so many cardioversions and ablations I can't count them. Last summer he had a hybrid ablation where they cauterized the entire back of his heart. He was in surgery for over 10 hours and went into shock. He was in ICU for two weeks on a ventilater and tube fed and sedated. Once he recovered he was fib free for 9 months. Now it's started all over again. It seems his choices are to live with it or get a pacemaker, even though the doc thinks he's too young for the pacemaker.
