I have been a patient at the Cleveland Clinic for a while now but I have not seen Dr. Jaeger before. I have an appointment with him in April and I'm just wondering what I can expect. What tests did he order for you? Was he helpful with finding the cause of your POTS and with figuring out a treatment plan that will work for you? Some background info that might be helpful: I'm a 21 year old female. I have Inappropriate Sinus Tachycardia and my EP thinks I may also have POTS so he referred me to Dr. Jaeger since he specializes in this. I have already had a blood volume and hemodynamics test (normal blood volume, minor to moderate blood pooling in legs), autonomic reflex test (normal), a QSART (normal), echocardiogram (normal), and countless EKGs (sinus arrhythmia but otherwise normal), and several holter and event monitors (showed average hr of about 100 bpm which diagnosed the IST). I have not had a tilt table test yet due to insurance not covering it. Also, I used to suffer from PSVT which got progressively worse until I was having 4-5 attacks a week and had to have an ablation done to get rid of the extra pathway. I had this done in December 2011 and so far it hasn't returned but my IST and POTS symptoms are still here. I have been on several different beta blockers. I'm currently taking propranolol. I also tried midodrine which did nothing for me and gave me terrible headaches and head pressure. I think that covers most of it.
