Today I tried the at home tilt table test I saw on this site. It is an Omron 10 Series which was recommended as being one of the better ones. Here are my readings: Lying down: BP 110/72 Pulse 84 After lying for 10 minutes: BP 107/72 pulse 80 Immediately upon standing: BP 92/74 pulse 122 3 minutes later: BP 95/81 Pulse 127 3 minutes later: error I kept repeating the test but it kept giving me errors after this point. It said E5 which means clothing is in the way of the cuff but I was wearing a tank top, so that's impossible. I'm thinking maybe the machine couldn't handle my readings? My mom, who is healthy, tried this test and her BP and pulse stayed very close to the same and the machine did not give her any errors. Has anyone ever had anything like this happen?
