I am in need of knowing what treatment is out there for tachy cardia ? Im a 33 yr old female diagnoised with sinus tachy cardia for 4 yrs and this last month my new primary dr gave me a 30 day event monitor and found my heart rate was hitting 180-200bpm . All these cardioligist i have seen say theres not much they can do put me on digitek which was working but now isnt and i know there there has to be something to calm my heart down before it kills me. I also wanted you all to know i have tried several beta blockers and other meds but i am look for solutions like surgery or a well known medication that has proven to be very effective. My doctors here are the worst in the world i swear so i am hoping a dr online will see this and help. ty.
