Help, Almost faint when waking

Recently I've been waking up several times a night with sinus tachycardia. When I bear down it goes away instantly. But sometimes I'll awake from a very deep sleep and feel almost dead, :( like I'm about the faint -- also with the tachycardia and what feels like very low blood pressure. Bearing down always brings it back to normal as the heart puts in a few really strong normal beats and the blood flow all normalizes and I begin to feel better - but what is that? I have no pain and I have never passed out. It's happening almost every night, but some nights I don't have any episodes.

The first two times this happened I went to ER and then followed up with a cardiologist. They can't find anything wrong.

Current Doc discovered I've had untreated Lyme since 2002
I'm starting treatment this week
And to add insult to injury, I've been diagnosed with autoimmune Hashimoto's and I have low thyroid hormone. Doc thinks Lyme triggered it. Going to see an Endocrinologist this week as thyroid also feels swollen.

The heart at rest beats a normal 70 bpm so I don't think it's hyperthyroidism since blood work shows hypothyroidism, and I ONLY experience the tach when sleeping. Resting blood pressure always slightly low at 105/70.

Thank you so much if you have any ideas or experiences as I could really use some sleep.:cool:

  • I totally understand what you mean, I feel the same way most nights, whereas others I wake up with palpitaions or a really slow beat that is heavy and almost painful. Ive been to the doctor a few times about the palpitations as i am also having them during the day. I can appreciate how awful it is to have your sleep interrupted like this! I've had a few tests done but nothing has come up on the results so doctors have told me im fine. It is getting very frustrating. I'm not even sure what they have tested me for!I hope you get some more answers soon. I wish i could.

  • I am sorry to hear you are also going through this. I'm finally getting some answers. Seems to be endocrine related (NOT HEART). So perhaps I should post questions on Endocrine Board now. But it does effect the heart. Low thyroid, possibly adrenal insufficiency is what my team of Doctors have all agreed on. Some tests still outstanding, but the early tests point to these. One normally doesn't associate tachycardia with low thyroid, but both of these conditions cause hypoglycemia AND that's the problem. I get low blood sugar in the middle of the night, my system responds by releasing adrenaline while I'm asleep, and that trips the tachycardia which wakes me up feeling faint and weak. Treat the thyroid, or adrenal fatigue, and you treat the hypoglycemia, and thus the tachycardia and palpitations should theoretically stop. I will let you know in few months.

  • That sounds like a perfect answer to my problem too, as when i first went with to the doctor with my palpitations she said it sounded like a problem with adrenalin release, but since then i've had other symptoms added, like the one you mentioned earlier. I've got an appointment with a cardiologist for a few weeks, but i feel like they wont find anything, as i'm convinced its an endocrine problem, but doctors dont seem worried enough to actually test me for any of that! I hope all goes well for you.

  • Well, you could look around for a more supportive endocrinologist. Do you also have the hypoglycemia type symptoms? I have learned those also occur with low thyroid. Ask for the anti thyroid antibody tests to see if it's autoimmune (Hashimotos), and make sure your endocrinologist is using the new scale for low thyroid (anything over 3) so you can get treatment if needed. The adrenal insufficiency testing is a bit more involved and there are various ways they can test for that. But it is important to rule that out before thyroid treatment. I just don't buy the simple answer a lot of cardiologists seem to give -- "well, heart's normal. Not sure what's causing palps or tach. Take this beta blocker." I would much rather get to the root of the problem. It would be so nice if cardiologists suggested that you see an endocrinologist if they thought that might help -- and that they would be willing to work as part of a team. Maybe some do. I just only recently found one, but it was hard finding him. I think Dr's are so specialized these days you really have to be your "general contractor"!

  • I also get the tachycardia on waking, it seems to start a second after waking, so I'm not sure if waking causes the tachy or vice versa. The doctor tells me I'm slightly hypocalcemic. I had my thyroid tsh and 24 hour urine catecholamines tested as all normal. Also been getting headaches recently, more pvts than normal, more chest pains than normal, more sweating than normal. Also feeling very adrenalised a lot of the time, though i went on a hypoglycemic diet and that has seemed to help. I eat loads and healthily but often feel undernourished. I'm stick thin but have lost quite a bit of weight recently also.I'm in a bit of a state. I wondered if for some reason I might be not absorbing all the good food I'm eating, because my symptoms seem to match malnutrition/anorexia.
