Hi, everyone, This is cut from a post at the end of a previous long thread because it's really a new topic now. Hope that's not breaking netiquette rules! My long awaited tilt table test was today. The results of the tilt itself were that the heart rate was normal, so I don't have POTS (I didn't think I did). The BP rate was a band of a squiggly line (I think the sys and dias alternating?) that was consistently the same width, and with the range often within normal. What the experienced cardio couldn't explain was that the whole band dipped and rose several times. He said this is indicative of falling asleep (not fainting) and had asked me at one point if I was OK, and at another point to open my eyes. Any wisdom on what that might indicate? Referred to a BP specialist now... Thanks!
