I started getting IST in may as well as 15000 PVCs a day i would get light headed and dizzy vertigo symptoms etc. It started a day after I had symptoms of a stroke. I have since undergone an ablation which was unsuccessful. It got rid of my pvc's that we have since found out were stopping another arrhythmia. Now I have PSVT and atrial flutter. I am unsure but I had a spinal injury a couple years ago that has slowly progressed if I turned my head to the right before I would have 3 times more palpitations. No one seems to listen to me when I tell them and they are not even checking. They want me to do another ablation and I don't know if that is the right thing to do. I had a structurally perfect heart and I feel like there is not any data on what will happen 30 years from now with that portion of my heart. I am more unsure if that is the right option. I really could use another opinion on what the best course of treatment is. I cant take this medication much longer it makes me very tired all the time and really lowers my bp.
