Module 01

3D Mapping Fundamentals

Learn how localization, geometry and intracardiac electrical data combine to create the 3D model you see on the mapping workstation.

Start module →
Module 02

Activation Maps & LAT

Activation mapping is fundamentally a timing problem: every mapped point is interpreted relative to a reference and an annotation.

Start module →
Module 03

Voltage & Substrate

Voltage maps visualize recorded electrogram amplitude. The challenge is understanding what that measurement does—and does not—say about tissue.

Start module →
Module 04

Propagation & Reentry

Propagation turns annotated timing into motion. Use it to visualize a hypothesis, then return to the electrograms to verify the story.

Start module →
Module 05

RF Ablation Concepts

Understand what RF energy represents, what the mapping system may display, and why lesion visualization is not the same as direct tissue measurement.

Start module →
Module 06

Pulsed Field Ablation

PFA is changing EP workflows rapidly. Learn the underlying concept and the technologist mindset needed to adopt new platforms responsibly.

Start module →
Module 07

Mapping Troubleshooting

Good troubleshooting is structured reasoning: define the change, localize the problem, verify it independently, and communicate precisely.

Principles before platforms

CARTO, EnSite, Affera and other systems differ in localization technology, hardware, interfaces, algorithms and workflows. EP Tech Hub focuses on concepts that transfer across platforms. Device-specific setup and operation must come from current manufacturer and institutional training.
