Orthostatic hypotension criteria include a drop in systolic BP and a heart rate rise within 2-5 minutes of standing. Is this statement true?

Explanation:
Orthostatic hypotension is diagnosed when standing causes a drop in blood pressure, reflecting a failure of the body's normal autonomic adjustments. The classic threshold is a decrease in systolic BP by at least 20 mmHg or diastolic BP by at least 10 mmHg within about 3 minutes of standing. A rise in heart rate may occur as compensation, but it is not required for the diagnosis. The standard time window is 3 minutes, not 2-5 minutes. So the statement isn’t strictly correct because the criterion centers on the BP drop, and a heart rate increase is not a required part of the definition, with the time frame typically limited to around 3 minutes.
