HOOK

Accurately identifying the source of abnormal heart rhythms is essential for effective treatment. Cardiac mapping provides detailed electrical and anatomical maps of the heart, helping physicians diagnose complex arrhythmias and guide catheter-based procedures with greater precision.

HISTORY / OVERVIEW

Cardiac mapping is primarily performed during an electrophysiology (EP) study. Specialized catheters equipped with electrodes collect electrical signals from different areas of the heart, while advanced mapping systems generate three-dimensional (3D) visualizations of cardiac anatomy and electrical activity.

Cardiac mapping plays a central role in planning and guiding catheter ablation procedures for many heart rhythm disorders.
