Supraventricular Tachycardia
"I am currently taking Cartia XT 120mg once a day, and it is a mixed bag for me.  I am still experiencing an elevated HR multiple times per day, and very light headed all day long.  I do not feel right at all.  I have also tried metropolol and lisinipril, having the best results from the latter, but it did not address my HR."
