A trainer built around UK practice: paper at 25 mm/s, the Resuscitation Council UK algorithms, NICE thresholds. Work through the ten chapters, then take the cases. Every strip below is drawn to real calibration — drag across one to measure it.
This is a study aid, not clinical guidance. The traces are synthesised to teach pattern recognition — real ECGs are noisier, and real patients matter more than their tracing. Drug doses and algorithms follow Resuscitation Council UK, JRCALC and NICE at the time of writing; check the current versions before you act on any of it. The EAC track and the scope, STEMI-threshold and escalation content are aligned to St John Ambulance's ECG for EACs revision guide (March 2026) and SJA Scope of Practice v1.3 — this site is not an SJA publication, is not affiliated with or endorsed by St John Ambulance, and where the two ever disagree, the official guide and your own training win. Never treat a rhythm you have only seen on a screen without assessing the patient.
