My son is 19, he was first found w/ high B/P when he was 17. He lost some weight and started to be more active and it became w/in good range. Recently for a job physical it was at 142/89. He had echo gram at 17, nothing was found. Is something else going on that can be checked?
First, you'd check both arms and make sure there really is hi blood pressure by taking it with the right size cuff and when the person is calm, lying down, and not talking. Then you'd look at organ damage with a simple blood test to check kidney and an EKG to check heart (but an echo is good too).
