概述
Orthostatic hypotension (OH) is defined as a sustained
reduction of systolic blood pressure (SBP) of at least
20 mm Hg or diastolic blood pressure (DBP) of 10 mm
Hg within 3 minutes of standing or head-up tilt to at
least 60° on a tilt table.1 The diagnosis can be made
easily at the bedside by measuring blood pressure (BP)
and heart rate supine and after 1 and 3 minutes of
standing.
