POTS, Tilt Table Testing, Neurocardiogenic Syn.

[crswin]

I went to my electrocardiologist today to discuss the results of my event monitor. I did have PVCs- which he says are benign. It also showed sinus tachycardia and some other 'minor' rhythm issues.
However, given my history of short 200+ bpm episodes and one case of a blackout, he wants to to a tilt table test. I am a bit nervous about this.  I have never actually passed out and am surprised about this test order. Has anyone had this done?
He stated that he is thinking about SVT, POTS, and/ or neurocardiogenic synscope.  He also gave me a handout about AV Node Reentrant Tach. (AVNRT) and Atrioventricular Reentrant Tachycardia (AVRT).  He stated that these may also be in the mix. I told him that I have never fainted, but since I have blacked out once and had palpiataions that have been at 200+ bpm for over 10 minutes, he still though this was necessary. I am a bit blown away by all of this and an looking to gather information.  My head was spinning when I left the office yestarday with so many unanswered questions that rely on these test results- I guess.
For the past 8 years, I have been told that my symptoms are neuro related, but later ruled out MS. I am new to the whole cardio world and am looking to learn all that I can. I really appreciate all of your input.
Does anyone have any experience or knowledge of SVT, POTS, neurocardiogenic synscope, AVNRT,  and/ or AVRT?
Thank you in advance for all that you can offer.

My daughter was diagnosed with POTS in Feb 2008 by tilt table test.  My son also had one this past December.  

My daughter's experience was short as she almost passed out within 10 minutes of being upright, so they discontinued with positive findings.  

My son's exam took longer and he was upright for about 50 minutes so for him it wasn't so much fun.

My understanding of the test is that you are laying on a hospital bed with an area at the footboard that will be under your feet once you are raised.  You remain laying down for awhile and are they monitor your blood pressure, etc. to see changes once they upright you.  They are checking for changes in blood pressure/heart rate and symptoms that may indicate positive findings,.

It really isn't that bad from what I understand.

Interestingly I took my daughter to a new doctor today who is a cardiologist/electrophysiologist and he said that he rarely needs to perform the tilt table test as he can usually verify diagnosis himself without it.  This is the first doctor she has seen who actually seems to know alot about POTS so we are looking forward to his help!

Good luck to you and let us know how it turns out!

I have seen discussion on this Community about most of what you ask, so I expect you'll see some helpful inputs.

The tilt table is one test I've never had, but it seems to be one that not difficult to take and it should rule in or out some of the issues in question.  So the good aspect is action is being taken to find out what is happening, and for there what can be done to make your life better.

Good luck,
