Learn electrophysiology one layer at a time.
Six standalone foundational lessons designed to take you from normal cardiac conduction to surface ECGs, intracardiac signals, EP timing, programmed stimulation and arrhythmia mechanisms.
Foundational learning path
Work through the lessons in order, or jump directly to the topic you need.
Cardiac Conduction
Follow the normal electrical pathway and connect anatomy with activation sequence.
Open lesson →Surface ECG
Build a systematic approach to rate, atrial activity, QRS activation and timing.
Open lesson →Intracardiac Electrograms
Catheter positions, A/H/V signals, CS sequence, bipolar vs unipolar recordings, near/far field and display settings.
Open lesson →EP Intervals
Understand AH, HV and the anatomical logic behind timing measurements.
Open lesson →Pacing Fundamentals
Drive trains, extrastimuli, capture, conduction and refractoriness.
Open lesson →Arrhythmia Mechanisms
Automaticity, triggered activity and reentry—and how mechanism-based thinking organizes EP.
Open lesson →How to use Learn EP
Read the concept, study the illustration, connect it to what you see in the lab, and then use the professional resources on each lesson page for deeper reading.
