I am a 53 y/o female in excellent health. Former college athlete and marathon runner. Always had mitral valve prolapse, PVCs, but onset of new systems this past Sept. Diagnosed in February with exercise-induced VTac, and then Bradycardia, and then total heart block shortly thereafter. HR dipped to 27 as I awaited results of Lyme disease test. It was negative, and His-pacemaker implanted. Now new issue with AFib event, and more adjustments needed for more voltage. Battery life of my 3 mo old pacemaker is now 4.5 years. Is is common to have so many different things all at once? I am on no meds and never have been. Looking for guidance before considering potential ablation and potential move of pacemaker lead. Everything seems so sudden, especially after losing my mom in August.
