| name | Orthostatic blood pressure | ||
| description | According to the American Academy of Neurology, the formal diagnosis of orthostatic hypotension requires a 20mm drop in systolic blood pressure or a 10mm drop in diastolic blood pressure within three minutes of standing. Often there is an associated increase in the heart rate, especially if dehydration or bleeding is the cause. (if the patient is taking a beta blocker, the heart rate may not be able to respond with an increase). | ||
