you may want to read and post in the heart rhythm forum; many of us there have had ablations, however i haven't ever heard of anyone having one done for vasodepression syncope - is this NCS? did the dr say neurocardiogenic syncope with vasodepressor symptoms? did they do a tilt table test to dx you?
I have NCS and OI - neurocardiogenic syncope and orthostatic intolerance related to heart conditions and I had a pacemaker/icd implanted to regulate my BP/HR so I don't faint - but also had an abltion for frequent arrhythmia's.
if you have NCS or OI that could be due to heart or ANS related problems - here's a great link with some info on it http://www.cccgroup.info/neurosyn.asp
make sure you ask lots of questions - normally the treatment for ncs/oi is salt/water loading, lifestyle changes, trigger eliminations and things like suppression hose - maybe what you have isn't the same?
Vasodepression syncope is because of a low heart rate or blood pressure, leading to inadequate circulation to the brain. This results in fainting, or loss of consciousness. The ablation is ususally done because of irregular heart beats. I haven't had any type of ablation, but from what I know about it, wires are run through an artery in the groin area up to the heart. The electrodes on the end of the wire locates the sight of the "misfire" (for a lack of any other reference) in the heart and the electrodes burn the tissue in that area. This is done to correct the "misfire" in the electrical impulses in the heart's rhythm. What has the doctor told you? There is a poster in this forum that has more experience in this and her name is Ireneo. Take care, Ally
