Cubs,
I was diagnosed with Lyme and Cos last May. In June, I began to experience constant Tachycardia; heart rate rarely below 130 and as high as 10 at rest. I also began to have POT symptoms. Heart was tested inside and out and found to be very strong with a good rhythm. the cardiologist was open to Lyme, but said that my symptoms were different than Cardiac Lyme.
After increasing the dosage of Metropolol a number of times (from 10 mgs to 200 mgs). My heart rate came down to 85 to 125 at rest, but the POTS symptoms remained and I actually feel more palpitations than I did when the hr was higher.
I also have a lot of neuro symptoms that my LLND does not feel all fit with Lyme. I was able to get in to see a top Neurologist in Boston who has ordered a number of tests including a tilt table test to be done early next month. He also wanted me to see the head of Cardiology at his hospital, whom I saw this past Monday. He diagnosed me with "Inappropriate Sinus Tachycardia". Fairly common in younger people and women, but not in adult males. He has kept me on the same med but split the dosage to half morning and half at night. He feels that Lyme could be a cause, but is not Lyme literate enough to be sure. He also feels that the med change will reduce the POTS over time.
Hope this helps
