Hello! I was diagnosed about a month ago with Supraventricular Tachycardia and put on Toprol. Then this past Tuesday I went to see a cardiologist and he said after look at my holter results he didnt see where the GP had seen SVT on it. He ran an echo (havent gotten the results yet) another EKG and ordered a tilt table test for Monday. He said he thought it could be Neurocardiogenic Syncope, also known as Vasovagal Syncope. However, when I looked it up everything says it goes hand and hand with a SLOW HEART RATE. He took me off the toprol so it would be out of my system for the Tilt test and my heart rate sped right back up. Anyone heard of this? Can you have Vasovagal Syncope with Tachycardia? Thanks for any help!!

Beerzoids your comments do not make sense. A cardiologist wanting to make money would NOT diagnose vasovagal syncope! He would maybe suggest an EPS.

Also you tend to relate everyone's symptoms to allergy. In your answer - allergy! This problem is nothing to do with allergy - or MCS either.

Normally having a high heart rate would indeed make you more susceptible to vasovagal syncope. Do you want to have something serious wrong?

As I say you think that allergies and chemical sensitivities are a major cause of illness. That is not true.

Your knowledge of the heart is sadly lacking. This person does not necessarily have SVT anyway, in which case your advice is superfluous.

I have to wonder about your motives beerzoids in relating everyone's illnesses to your own?

For example why would an increased sympathetic activity increase vagal tone? You do not give a convincing link between chemical exposure and vasovagal syncope.

As I say you think that allergies and chemical sensitivities are a major cause of illness. That is not true.

It depends upon the illness. Allergies and chemical sensitivites ARE a major cause of ailments. When the body misbehaves, and the doctors cannot find structural damage within the body, the most obvious cause would be that something in one's environment is causing the ailment.

Your knowledge of the heart is sadly lacking. This person does not necessarily have SVT anyway, in which case your advice is superfluous.

You don't prove your own wisdom on an issue just by discounting completely someone else's knowledge. Prove me wrong that the endocrine system is not a huge cause of the heart misfiring. I can show you THOUSANDS of medical articles showing that I am right.

If you are interested, do a little research in this area. You will be amazed at what you could learn. :)

You sound stressed out and angry. I can understand the meaning behind your nickname.

Sit back, close your eyes and take deep breaths. Take two aspirins and call me in the morning. :D

First of all beerzoids is the cause of this person's problems SVT? Apparently not. Of course the adrenergic system affects ectopic activity (although it is not the cause of ectopic activity as you incorrectly imply). In fact atrial ectopics are often due to foci in the pulmonary veins.

You are on a crusade to prove that chemical sensitivity is a major cause of illness - however the evidence does not support that. There is not even evidence that multiple chemical sensitivity syndrome exists. People here want advice, not to be a pawn in your personal crusade.

Beerzoids surely bad advice must be recognised. This poster was asking about tachycardia and vasovagal syncope, a question which I have answered.

You have a problem with transferrence obviously. What are you angry about? You mention open-mindedness in such a context that I equate with credulity and gullibility. Do you recommend ozone therapy or NAET?

Your advice would harm someone beerzoids - unfortunately. Ignorance is one of the most dangerous things in the world.

I expect you don't know what my screen name alludes to?

Typhoidmary, Thank you for your input. I completely agree with you about Beerzoids. I do not have allergies of any kind and am VERY careful about what chemicals I come in contact with. I wanted to see a cardiologist. I asked my GP for the referal to be able to go to the cardiologist. When he read the results from my holter (that the GP had read and said it was SVT) the cardio said he believed it was an incorrect diagnosis. Thats the reason he ran more tests and I was more then happy to comply. I want to fingure out what is REALLY going on not just treat something that it might be. The toprol slowed my heart and the cardio said he might put me back on it but I cant be on it while I have the tilt test done or the test wouldnt show anything. I had been wanting the echo done since all this started to make sure myheart was okay and healthy. It shouldnt start going into tach just because there has to be a cause. I just dont know much about Vasovagal Syncope and I wanted to hear what others knew from their personal experience. Thank you for all your help.

The slow heart rate is part of the reaction, the syncope. I have neurocardiogenic syncope and I have inappropriate sinus tachycardia. With the NCS reflex my heart rate and my bp drop simultaneously.
My EP thinks that my tachycardia may be a trigger for the NCS. I take a beta blocker for the NCS and I take a calcium channel blocker to help with the tachy. (I can't take a big enough dose of bb's to control the tachy w/o side effects).

Thanks a lot jpos! THat was very helpful. I leave for my tilt table test in 5 minutes!!
