this past year i got sick. then it followed with unexplained nerve inflamation throughout my entire body, that has gone, but throughout this year i have ahd rapid heart beats boundinding heart beats , getting winded easy, .. bounding so bad it would wake me up at night, was put on beta blockers a montha go seems to help but still is going on. i had a enlarged multinodule tyroid which was suspicous of cance , which was entirely removed last week, a cardiolgist in the hospital was called to see me because i had a atrial fibrulation while being operated on, iu have an appt. this week witha cardiologist. the hospital cardiologist thiks it was realted to the tyriod and aftera fewq weeks on the correct hormone anmounts it will resolve itself, before the surgurey my blood was tested and it showed normal tyroid function. do you think its still possible fotr that to be right. does the thyroid hormone regulate your heart funtions or is it just have to do with energy, metabolism, speed of heart? thanks for info Kevin
