Electrophysiology (EP) in a hospital is a specialized medical field that focuses on studying and diagnosing electrical activities in the body, particularly the heart. This branch of cardiology utilizes advanced technologies to analyze the electrical impulses that regulate the heart’s rhythm and function. In a hospital setting, electrophysiology procedures are often conducted in a dedicated EP lab equipped with state-of-the-art equipment, including specialized catheters, imaging systems, and monitoring devices. Cardiac electrophysiologists, highly trained medical professionals, perform a range of diagnostic and therapeutic procedures, such as electrophysiological studies (EPS) and catheter ablations, to identify and treat various cardiac arrhythmias. These procedures play a crucial role in managing patients with heart rhythm disorders, enhancing the overall quality of care and contributing to improved patient outcomes in the field of cardiology.
