The Heart's
Electrical Story
A mechanism-first journey through cardiac electrophysiology in eleven volumes.
From the ion channel to the implanted device: understand the why before the what.
The EP Lab
A full electrophysiology lab driven by a conduction model of the heart. Place catheters, pace from any site, give drugs, map and ablate. Every electrogram is computed from how the impulse travels, so each maneuver answers the way real tissue would.
Open the EP LabWork through 15 guided lessons, try any of 28 sandbox hearts, or run an unknown case and get a scored debrief.
Why this exists
This platform teaches cardiac electrophysiology from the membrane up. Every explanation begins with the movement of ions, the behavior of channels, and the architecture of tissue. The surface ECG appears later, as a consequence of what the cells are doing.
The core principle is straightforward: define the mechanism and the site of an arrhythmia before proposing a treatment. Understand what the circuit is, where it lives, and how the electrophysiology study proves it. Then choose your intervention.
This is electrophysiology taught as a story.
Mechanism First
Before we name a rhythm or reach for a drug, we open the cell and look at the mechanism. If you understand the machinery, the clinical picture makes sense on its own.
Prove it
The EP lab doesn't guess. Entrainment, pacing maneuvers, and intracardiac recordings give you the evidence. We'll learn how to read it.
Layered Depth
Start with understanding the mechanism, then go deeper. Every topic is written so a medical student can follow along and a fellow can find the detail they need.
The Story Map
Eleven volumes. 69 chapters. One continuous narrative, from the resting cell to the implanted device.
From Cell to Cath Lab
Every concept in this platform follows the same ascending ladder, from molecule to treatment decision.
