Karen - i am unable to tolerate any meds including florinef, octreotide, beta blockers etc. i am extremely sensative to all chemicals - meds etc - this is due to the POTS - was not like this before. the pacemaker did not stop my problems it has actually made them much worse. it only controls my brady symptoms but i still have severe arrythmyias because my heart still wants to race but cannot due to the damage from the ablations. my bp ranges from 90/60 and down. i am unable to care for my children - cannot shower, shave my legs, cook, brushing my teeth is difficult and someone has to wash my hair.. i am having severe muscle weakness and i fall daily.. i never thought that this would go this far.. i was in optimal physical condition prior to having my daughter - i actually jogged 2 miles the day before she was born and now i cannot walk 20 ft without haivng to sit down. the doctors say that my case is now very difficult and are not sure what to do.. i will be going to a new specialist soon as my other one is at a loss for why this is progressing so quickly... i have been told that ablations are the worst thing in the world for a person with POTS but we simply did not know that is what was wrong with me ( i had never heard of it) - i was originally dx with SVT, PSVT, inappropriate sinus tach, A-fib and aflutter. All symptoms of POTS but it was too late the damage was done - i am soooo glad that i found this site.. i was beginning to think that i was alone and now i know i can find hope that this may get better!!!
