👤 Harold, 73, admitted after fall at home

Meds: lisinopril + furosemide + tamsulosin (triple OH risk)

Baseline (5min supine): 142/84, HR 72
1-min standing: 126/78, HR 80 → drop of 16 mmHg (NEGATIVE)
3-min standing: 118/70, HR 84, "a little lightheaded" → drop of 24 mmHg (POSITIVE)

⚠️ If you stopped at 1 minute, Harold goes home with no diagnosis — and falls again.

The 3-minute measurement made the difference.
