From signals to 3D strategy.
A seven-module, principles-first course for EP technologists: mapping fundamentals, LAT, voltage, propagation, RF, PFA and structured troubleshooting.

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 →Activation Maps & LAT
Activation mapping is fundamentally a timing problem: every mapped point is interpreted relative to a reference and an annotation.
Start module →Voltage & Substrate
Voltage maps visualize recorded electrogram amplitude. The challenge is understanding what that measurement does—and does not—say about tissue.
Start module →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 →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 →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 →Mapping Troubleshooting
Good troubleshooting is structured reasoning: define the change, localize the problem, verify it independently, and communicate precisely.
Start module →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.
