Orthopnoea in a patient with left ventricular insufficiency typically starts:

  1. A. late after lying down, it awakes the patient, and subsides after ≥ 30 minutes of verticalization.
  2. B. late after lying down, but it does not awake the patient, and subsides after ≥ 30 minutes of verticalization.
  3. C. right after lying down and it subsides promptly after standing up or sitting.
  4. D. 1-2 minutes after lying down and it subsides a few minutes after standing up or sitting.
  5. E. 15 minutes after lying down and subsides after ≥ 30 minutes of sitting.
Hint

Distinguish orthopnoea from paroxysmal nocturnal dyspnoea by how soon breathlessness starts after lying down and how quickly it settles on sitting up.
