Hi littleflowers, welcome to the heart forum. I have bradycardia (low heart rate) and orthostatic hypotension (low bp). I take 4 differant medications throughout the day to maintain my BP at a normal level. Sometimes they end up pushing it up into a high range, which my cardiologist and PCP are not concerned with as this is their goal in my treatment to keep my BP up.
However, I dont know much about Lyme disease and its effects on BP or if it effects BP. I imagine it very well could. 150/100 is awfully high as is 140/100. I would think that the physicians would want to see a consistant amount of increased BP's before they treated you for high blood pressure. If you have a monitor at home you may want to take some readings of your own and record them for referance to show your docs.
