History of Presenting Complaint

Overview

With each symptom, always (if relevant) ask about:

  • When did it start?
  • Did it come on suddenly or gradually?

Investigations

Overview

Key initial investigations:

  • ECG – should be done as soon as possible:
    • May show changes consistent with a cardiac disorder (e.g. STEMI)
  • Cardiac troponins:
    • If acute coronary syndrome suspected
  • Chest x-ray:
    • If respiratory disorders are suspected
