Orthostatic tolerance appears stable across repeated tests in healthy males; leaves open symptom variability and applicability to patients.
Is individual orthostatic tolerance stable across repeated combined head-up tilt and lower body negative pressure tests in healthy young males?
While orthostatic tolerance times are relatively stable within individuals across repeated testing, the specific presyncopal signs and symptoms can vary, highlighting the need to monitor both during testing.
Goswami et al. (2009) studied this question.
