With the evolution of modern interventional cardiology techniques, the cardiology suite has become a frequent place where the diagnosis and treatment of patients requires the use of procedural sedation. The cardiology suite is designed to meet certain safety parameters. It is typically divided into two main areas, the procedure room and the control room. All patients to be scheduled for an interventional cardiac procedure should undergo a rigorous screening and detailed pre-procedure evaluation for medical risk factors that might predispose the patient to complications during the procedure. This lists the interventional procedures commonly performed in the cardiac catheterization and electrophysiology laboratory, along with their sedation requirements and complications. A unique characteristic of many of the procedures performed in the cardiology suite is that they involve brief periods of intense stimulation followed by long periods of minimal stimulation.
