Registered Cardiovascular Invasive Specialists (RCIS) are proficient in the use and application of analytical equipment. They prepare patients for diagnostic and interventional procedures and examine patients at the request or direction of the physician. Through sampling and recording, technologists provide a foundation of data from which precise anatomic and physiologic diagnosis may be established. The term RCIS is new. It was previously Registered Cardiovascular Technologist, RCVT.
