Originally, i had A-Fib.......Taking Coreg & Tikosyn........My heartrate then became slow & Doc said to discontinue Coreg.........after a while, I became weak all over & Doc took me off of Tikosyn ,because he said I had developed a more serious condition of Ventricular Tachycardia......After a few days, my weakness & feeling like i am going to pass-out has overcome me again.........am listed to take a 24 hour holter monitor and echo cardiogram nine days later........also, am having 2 decayed teeth extracted in a couple of days..........Can you comment/advise on my condition/situation ?
