What is a cardiovascular ultrasound technologist?

A cardiovascular ultrasound technologist performs echocardiograms — ultrasound scans of the heart's structure and function — and vascular ultrasound studies. It is a non-invasive role: no catheters, no radiation, just sound waves and skilled image acquisition. The sonographer captures the images and measurements that a cardiologist interprets.

Credentials

Echocardiography credentials include the RCS (Registered Cardiac Sonographer, from CCI) and the RDCS (Registered Diagnostic Cardiac Sonographer, from ARDMS). Both require an eligibility pathway plus an exam. Vascular sonographers pursue the RVT or RVS.

Cardiovascular ultrasound technologist salary

Cardiac sonographers are grouped with diagnostic medical sonographers, who generally sit toward the higher end of the cardiovascular-technologist pay band. Figures vary by region and setting — check the current median on the BLS Occupational Outlook Handbook, and see our salary guide.

Frequently asked questions

What is a cardiovascular ultrasound technologist?

A non-invasive cardiovascular technologist who performs echocardiograms and vascular ultrasound — imaging the heart and vessels with ultrasound rather than catheters.

What credential does a cardiac sonographer need?

Commonly the RCS (Registered Cardiac Sonographer, from CCI) or the RDCS (from ARDMS).

How is it different from an invasive cardiovascular technologist?

Ultrasound technologists use non-invasive ultrasound with no radiation; invasive technologists assist catheter-based procedures in the cath lab and hold the RCIS credential.

What is the salary of a cardiovascular ultrasound technologist?

Cardiac sonographers generally earn toward the higher end of the field; check the BLS Occupational Outlook Handbook for current median wages.
