Cardiac condition symptoms and conditions

I took Avelox a couple of months ago to treat a urinary tract infection which i thought was kind of strange. About two tays later i started getting severe heart palpitations. It felt as if my heart was going to explode from beating so fast. I almost went to the hospital but stopped myself when i thought it could just be anxiety. I called the doctor after 3 days of taking it and he said that my symptoms could be side effects of Avelox but were rare. Ill tell you one thing i will NEVER take Avelox again and i dont recommend that anyone take it unless absolutely necessary.
