How fast
Go now
Drop what you're doing unless it's sicker.
Ask on the phone
- Character, onset, still ongoing?
- Obs, especially BP in both arms if possible.
- Known cardiac history? Post-op?
Every bleep: the basics
- Name, ward, bed, age, why they're in hospital.
- Full set of obs and the NEWS2 score — and what it was before.
- Resuscitation status (DNACPR / ReSPECT) and ceiling of care.
Ask the nurse to start
- 12-lead ECG now and keep it for you to see.
- Oxygen only if SpO₂ under 94%; IV access; troponin.
Call your senior if
- ST elevation or new LBBB, low BP, or ongoing pain with ECG changes.
When you get there
For healthcare professionals, as an aid to clinical judgement — not a substitute for it. Follow your local policy and ask a senior when in doubt.
