Upright tilt and the Valsalva maneuver are better predictors of autonomic function in hypertension than the sustained handgrip test.
No takes yet. Share an insight, caveat, or question.
Tilt and Valsalva may better detect autonomic differences than handgrip in hypertension; hypothesis-generating and requires prospective validation before any practice change.
Steven G. Chrysant (1982) studied this question.
