What is an EP exam in Cardiology?

An EP exam, or electrophysiology exam, in cardiology is a specialized diagnostic procedure that evaluates the electrical activity of the heart. It typically involves threading catheters through blood vessels to reach the heart, where doctors can assess heart rhythms, locate abnormal electrical pathways, and determine the cause of arrhythmias. This procedure can also be used to guide treatment options, such as catheter ablation for certain heart rhythm disorders.
