The Basic Language of Cardiac Electrophysiology—An Introduction to Intracardiac Electrograms and Electrophysiology Studies

  • Sandeep Prabhu

This chapter aims to introduce the reader to some of the core principles which underpin clinical cardiac electrophysiology and how it is applied in cardiac catheter laboratories, where ablations take place. Key language and terminology are introduced before these concepts are explored further in subsequent chapters.
