I made an error the 140 was for 23 beats. There were others like 120 but it does not say for how long.
You don't give your age (though I have the feeling you are not elderly), and have passed your heart exams many times, so your ticker is almost certainly healthy. The low pulse rate might have been related to something like bigeminy, where every other beat is dropped or out of time. Since the pre-snycope episodes occur even when you're sitting, I--having had the same experience--would hazard a guess (given your tests) that you are indeed experiencing Vagal symptoms. Some people are just more sensitive to signals from inside their bodies, and the irony is that the more you 'listen' to these signals, the twitchier the Vagus becomes.
Again, speaking from years of personal experience, I would suggest you consider two things (bearing in mind that your tests have shown you to have a basically healthy heart):
1. Can you perform all your normal activities without drenching sweat or central chest pain, things like walking, housework, going up stairs--when you're not thinking about your heart?
2. If you can, the chances are miniscule that you have some underlying condition that will cause you to die suddenly, and the chances are great that you are suffering more from a kind of anxiety disorder. I am not being judgmental: This kind of thing simply happens, generally without any predisposing traumatic event. My personal suspicion is that it's a genetic trait.
Cognitive behavioral therapy and certain mental exercises with a good counselor can help, but because my symptoms come on suddenly every few years, without a precipitating event, I favor medical treatment with an anti-anxiety drug.
HI there and thank you for your response. I know that I am not going to have a heart attack:) I had a negative Angiogram in early may of this year, I was having awful chest pains and my cardio wanted to rule out my heart, I think it was my gallbladder and had it removed, I still have pains here and there but not as bad. Sorry I forgot to put my age and I am 28.
I just worry about an electrical problem. I do have a history of SVT and thats the reason for the EP study in 2004 but it could not be provoked long enough for mapping so we just left it alone and I rarely have an episode so we just let it be.
I hope that it is what you mention because we are running out of things here. I have had many test so far and all is well. The only other thing noted was a nystumas, fast beat to the right in my eyes which they thought was caused by ears and so was sent to an ENT which cleared my ears and now I have to go back to the neuro.
I have seen a mental health doctor but she felt anxiety was not causing my problem. I have had an anxiety and panic attacks in the past so I thought it worth a try even though it does not feel the same. She sent me back to my primary.
The Vagus is a long and very weird nerve with many functions. In some of us, it behaves quite badly, making us likely to faint when we feel odd internal sensations, or even when we get overheated (I do this sometimes in the summer, and have scared the cr*p out of a couple of restaurant owners). Tilt-testing is one way to check if you have an abnormal vagal response, btw. Here's info on vasovagal syncope, and there's lots more out there:
I will check out the info you provided. I will be having the tilt test soon... I have not passed out yet thank goodness but each episode seems to get longer each time even though its just seconds. I also have an appointment with the EP doctor who did my study next week.
Do most people with the vagus nerve just get it one day, or is it something they have had their whole life? Can people with this problem just be lightheaded and never faint?
We all have that lovely Vagus nerve:
but I think the tendency for it to fire inappropriately and produce the kind of trouble we're talking about is something that occurs in a minority of people who have a tendency to be hypersensitive as adults. I do have the impression, based on my own experiences, that paying too much attention to little internal 'noises' and getting too fearful about them causes more adrenaline to be released, which worsens the situation. That's why it's good to get help with anxiety and panic.
Oh, as to fainting, I've only actually fainted dead away once, and that was the result of pain from a severe intestinal infection. The other near-faint things have been momentary or went away (of course) when I lay down or put my head on my knees. There is another effective and easy way to prevent fainting, though, as described here:
"...crossing the legs or tensing the leg, buttock and abdominal muscles, is enough to stop blood pooling in the legs - the main cause of fainting."
