Ok I know you all think I am nuts but this is what is happening.I couldn't work it out last night ,just kept waking all night and tonight I realised what is happening.
Anyone else had this??
Sue from Downunder.
I have this quite frequently. Recently I got a blood pressure cuff, thinking maybe my blood pressure went up, cause I could feel my blood pounding.
Instead I found my blood pressure would be very low, with a very rapid heart rate. we are still trying to find out what causes it.
One thing I've found that may be part of it, is that it is more likely if I am dehydrated. Less blood volume causes the heart to beat faster in order to get enough blood where it needs to go. So, I'm trying to drink more.
So far, my strees EKGs came back normal, and my thyroid meds are a little on the low side, so we're still looking.
I get the pounding heart & night sweats when I got to bed and I have had the shooting pain behind my eye in the past.
I have tested positive for Babesia and my LLMD thinks I have Bartonella too. I would consider treatment for both of these.
Hope this helps
Emma
Healthy thoughts to you.

I have the heart racing too, although it is under control with medication.
It started the day I pulled out a tick, and has never gone away. I am pretty darn sure there is a babesia connection. The sweats and any low fevers can be Lyme but they can also point to co-infection with Babesia.
My blood pressure runs low, and I get orthostatic. I also get the pounding heart rate, and I am on atenolol for that.
I would ask your LLMD to refer you to a Lymeliterate cardiologist and have a Tilt Table Test done with Isuprel challenge. The test will determine if you have the heart problem, the blood pressure problem or both. Both of these measure Neurally Mediated Hypotension which is caused by the bacterial inflammation of the central nervous system. the vagus nerve leading from your heart to your brain malfunctionsand the result can be one or more components of NMH.
Ask me if you have any questions, I have been dealing with this for 3 years.
I have a set of links near the bottom ofmy lymelinks page on my website.
Cheers!

Some people here have speculated that there may be some (still unexplained) relationship between apnea and lyme. To that end I'll offer an alternative explanation, for whatever it's worth.
People with obstructive sleep apnea (OSA) often wake repeatedly (as a result of the periodic suffocation, of course). When they become hypoxic (during the episode of suffocation, or "apnea") and then start breathing again they can eperience tachycardia. Here's an explanation of that (HR = heart rate):
"Hypoxia has varying influences on HR according to the presence or absence of airflow, and the balance of its parasympathetic and sympathetic stimulatory effects. In the absence of airflow, hypoxic stimulation of the carotid body is vagotonic, and causes bradycardia (45, 46). Conversely, in the presence of airflow (e.g., hypoxic rebreathing), hypoxia causes tachycardia because stretching of the lungs inhibits vagal outflow to the heart and permits unopposed cardiac sympathetic discharge."

OSA can also cause nightsweats, which you mentioned. (Breathing cools you off, so apneas can lead to overheating; though you may not wake up until you've started breathing again and have become chilled).
Most people with OSA don't know they have. It is common, causes sleepiness and fatigue, and leads to cardiovascular disease. And just because you have lyme doesn't mean you can't be blessed with other diseases :-)
I've experienced these episodes myself and it is in part for that reason that I use CPAP, even though I tested negative (there is a 25% rate of false negatives on the overnight test); I'm not taking any chances.
Feel better,

I had this same thing a few times and my doctor thought it was because keets were being killed in the heart tissue at the time.
I got rid of this and many other symptoms with IV Rocephin in combination with oral abx.
Hope you feel better soon and can get some rest!
