The Heart's Electrical Story

The Heart's
Electrical Story

A mechanism-first journey through cardiac electrophysiology. From the ion channel to the EP lab — understand the why before the what.

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

Seven volumes. One continuous narrative. Each builds on the last — from the resting cell to the ablation catheter.

From Cell to Cath Lab

Every concept in this platform follows the same ascending ladder — from molecule to treatment decision.
