electrophysiology study (EPS)

An electrophysiology study (EPS) is a specialized procedure used to evaluate the electrical activity and functioning of the heart's conduction system. During the test, thin flexible wires called catheters are inserted into blood vessels and guided to the heart. These catheters measure electrical signals, identify abnormal pathways, and assess how the heart's rhythm is generated and maintained. EPS helps diagnose arrhythmias (irregular heartbeats), determine their cause, and guide treatment options such as medications or procedures like ablation. It provides detailed insight into the heart's electrical behavior to ensure accurate diagnosis and effective management.
