I have been prescribed to Flecinide because of very frequent PVC'S like 10-13 per min. All day except when I fall asleep. My EP docter told me I had two options. 1) Ablation 2) Medicine to surpress these darn things. He said that because te PVC's that I am having look to be in a tough spot to ablate at this time that Flecinide would be better for me. So I took the Flecinide and still am taking it 6 months later. My life is completly back with no PVC's at all. Man it feels good but after talking with several people is Flecinide worth the risks. My heart is structualy normal but now I am worried about what the medicine will do to me. I also run 3 miles a day and sometimes feel bad after excersise light headed etc. Just wanted to see if anyone else is taking this or knows anything about it.
