An Investigation of Heart Rate Recovery Responses to Repeated Active Stand Protocols

The participant is asked to lie down for 10 mins without moving or speaking. A heart rate monitor is attached while the participant is lying down. They are then asked to stand up as quickly as possible and to remain standing unassisted for 3 minutes. The participant will be asked to describe any symptoms at 1 and 3 minutes after standing. Blood pressure and heart rate will be monitored constantly throughout the test.
