ECG Cases: EKG Interpretation

ECG Cases is ECG interpretation practice on real 12-lead EKG recordings from patients, not drawings. Each quiz case shows the full 12-lead ECG with a lead II rhythm strip: pick the finding, then see which leads give it away and why. Built for medical students, nursing students, nurses, paramedics and junior doctors preparing for exams or ward work: practice questions with answers, a timed exam mode, short lessons, calipers and five new cases every day. No account, no ads, works offline. REAL 12-LEAD ECGS YOU CAN TRUST • 940 recordings from real patients, labelled by cardiologists • A recording is used only when the cardiologist's diagnosis and an independent computer analysis (12SL) agree, and its measurements meet the criteria for that finding • Printed the standard way: 12 leads, a long lead II rhythm strip, 25 mm/s, 10 mm/mV and a 1 mV calibration pulse • Pinch to zoom into any complex EVERY ANSWER EXPLAINED • The leads that matter are tinted on the tracing, and the tracing stays on screen while you read • Heart rate, PR interval, QRS duration, QTc and axis of that very recording • The criteria for the finding, in plain words • Wrong answer? You see what you chose and what it really was MEASURE LIKE ON PAPER Drag the calipers across the tracing to measure any interval in milliseconds, with the matching heart rate. WHAT YOU PRACTISE • Rhythm: normal sinus rhythm, sinus tachycardia, sinus bradycardia, atrial fibrillation, paced rhythm, premature ventricular complexes • Conduction: first degree AV block, left bundle branch block, right bundle branch block, left anterior fascicular block • Infarction and hypertrophy: inferior myocardial infarction, anteroseptal myocardial infarction, left ventricular hypertrophy • Answer options are chosen from the findings most often confused with the right one 16 SHORT LESSONS One page per finding: how to recognise it, where to look, common traps, and real example recordings. Also covers atrial flutter, Wolff-Parkinson-White and long QT. 5 NEW CASES EVERY DAY A short daily set, mixed practice or practice by group, a daily streak, and your score for each finding so you can see what still needs work. IN YOUR LANGUAGE English, Spanish, Portuguese, French, German, Indonesian, Turkish, Arabic and Vietnamese. FREE AND PRO Free: five cases for every finding, five new cases each day, all 16 lessons and two examples per lesson. No account, no ads. ECG Cases Pro is a single purchase, not a subscription. It opens every case, every example, the calipers, timed exams and the review of the cases you got wrong. WORKS OFFLINE Every recording is inside the app. Nothing you do in the app leaves your phone. GOOD TO KNOW • The recordings come from the PTB-XL and PTB-XL+ open datasets on PhysioNet (Wagner et al., Strodthoff et al.), used under the Creative Commons Attribution 4.0 licence. Full credits are in the app. • ECG Cases is a study aid. It is not a medical device, it does not interpret your own ECG, and it does not give medical advice, diagnosis or treatment.
