Cardiac electrophysiology study, diagnostic maneuvers and ablation

Abstract

The overall aim of an invasive electrophysiological (EP) evaluation is to accurately diagnose the mechanism and substrate responsible for a documented or suspected arrhythmia in order to treat the patient's symptoms or improve their prognosis. Significant developments in the understanding of arrhythmias as well as evolving technological advances have allowed electrophysiology studies to be considered as a diagnostic first-line option. This chapter discusses the fundamental principles of invasive electrophysiology and provides an essential guide in terms of establishing the correct diagnosis and ablation strategy.
