License and training

Most states do not license this work directly. Employers usually ask for a credential from Cardiovascular Credentialing International, such as RCIS or RCS, or from ARDMS for echo. A few states license imaging or sonography staff, so confirm the rule in your state before you hire or start.

The work

A cath lab day starts with a room set up for a case that may move up the schedule. You scrub, monitor, or record, and you may be on call for a heart attack at night.

Noninvasive work is steadier. You run an echo or a vascular study, capture clean images, and hand the reader a study that answers the order. A stress test adds a patient who needs coaching and watching at the same time.
