## What is ECG School?

ECG School teaches ECG interpretation the way it is actually learnt: by looking at many traces, measuring for yourself and making decisions in realistic cases.

CHOOSE YOUR LEVEL
• Layperson – understand what the trace shows, recognise dangerous signs and know what to do in a heart attack or cardiac arrest. No prior knowledge needed.
• Nurse – systematic interpretation from electrode placement to STEMI equivalents, bradycardias, tachycardias, electrolytes and prehospital management. 11 lessons and 12 cases.
• Physician – vectors and fascicular blocks, differentiating narrow and wide tachycardias (Brugada, Vereckei), subtle occlusion (aVL, Smith's formula, the aneurysm rule), Sgarbossa/Smith, pacemaker malfunction, channelopathies, QT correction and ladder diagrams for difficult rhythms. 7 lessons and 9 cases.

HOW IT WORKS
• Every trace is drawn by an ECG engine at 25 mm/s and 10 mm/mV – each pattern is clean and measurable.
• Calipers under every trace: measure time, rate and amplitude with two taps.
• Interactive graphics: the conduction system phase by phase, electrical axis and injury vector with sliders, coronary arteries and lead territories, an annotated heartbeat, ladder diagrams (laddergrams).
• Deep dives explain why: ion channels, vectors, why LBBB gives discordant ST-T, why inferior infarction causes AV block.
• A quiz after every lesson and patient cases with multi-step decisions. Progress is saved on the device.
• Glossary with 77 terms and a quick reference for each level.
• Works fully offline. No accounts, no ads, no data collection.

TRY FOR FREE, UNLOCK ONCE
Download for free and try the first lesson at each level (two at the nurse level) and one patient case per level. The full version is a one-time purchase that opens everything, for ever, including future lessons. No subscription.

THE CONTENT IS BASED ON
The ESC guidelines for acute coronary syndromes (2023), cardiac pacing (2021), supraventricular (2019) and ventricular arrhythmias (2022), the Fourth Universal Definition of Myocardial Infarction, published criteria (Sgarbossa, Smith, Brugada, Vereckei) and the Swedish Resuscitation Council's and 1177's advice to the public.

ECG School is educational material and does not replace clinical judgement, supervised training or local treatment guidelines. If you suspect an acute illness: call the emergency services.
