ECG Learning Library
Interactive, programmatically rendered ECG tracings with adjustable parameters, synchronized ladder diagrams, and conduction animations. No static images — every waveform is generated in real time.
ECG Topics
Each topic features real-time waveform rendering with interactive controls, play/pause/step navigation, and synchronized anatomic animations.
AV Block Spectrum
Interactive exploration of all AV block types — from first-degree through complete heart block. Adjustable PR intervals, conduction ratios, and escape rhythms with synchronized AV node conduction animation and ladder diagram.
Hyperkalemia Spectrum
Interactive K⁺ slider from normal through peaked T waves, widened QRS, sine wave, and cardiac arrest. Real-time ECG morphology changes with serum potassium level.
Long QT Syndrome
Genotype-specific T-wave morphology for LQT1, LQT2, and LQT3. Adjustable QTc with real-time waveform changes and torsades de pointes simulation.
Wide Complex Tachycardia
Interactive Brugada criteria algorithm for VT vs SVT with aberrancy. Adjustable QRS morphology with real-time scoring and step-by-step differentiation.
STEMI by Territory
12-lead ECG view with interactive ST elevation by coronary territory. Anterior, inferior, lateral, posterior, and RV involvement with reciprocal changes.
Atrial Flutter & Fibrillation
Interactive atrial rate slider showing flutter with variable block (2:1, 3:1, 4:1) transitioning to fibrillation. Sawtooth morphology and irregular RR intervals.
About This Library
All ECG tracings are programmatically generated using mathematical waveform models — they are not recordings from real patients. While designed to be realistic for teaching purposes, they should not be used for clinical diagnosis. These are educational resources for cardiology trainees, fellows, and practicing clinicians.
