Thought it would be interesting to ask if you had a pacemaker implanted following valve surgery? If so which valve do you have and how soon after your OHS was it determined that you needed a pacemaker? I am particularly interested because my cardiologist tells me that based on a recent EKG and follow-up with a heart monitoring device that I have intermittently shown signs of stage 3 heart block with my HR dropping to the low 30's. I have had no negative symptoms and my MV replacement surgery was 8 years ago. I am told that the atrioventricular conduction system is very close to the mitral valve and that the AV Node was probably negatively impacted. I have resisted calls to go to the emergency room because it doesn't make sense to me that I have been fine for 8 years and still feel fine. I guess my tombstone will read "Died from an acute case of stubbornness".
