I did the squat/stand test again this AM. took 2 readings in each position about 1-2 minutes apart. I graphed them and they look like the CAN patient's graphs, although less marked - more gentle appearing on the graph. I didn't have any of the spikes or drops that the healthy groups had. I had a stable, even 10 point rise in systolic BP from stand to squat, and a 10 point stable drop on squat/stand transition. My HR started around 68-70, dropped to 58-60 during the squat, and back to 67-70 during squat/stand transition. Of course, by beta blockers are still affecting me this morning, but my results seem to mimic the CAN results. I heard this morning from a Doctor's webcast that if your BP doesn't rise by 10 points both systolic and diastolic when going from sitting to standing, there's an autonomic problem. My BP didn't change at all. I did it 2-3 times. Only once I got a 5 point change in both sys & diastolic, but the other 2 times, no change at all. even after 3 minutes standing. this could be the beta blockers.
