What's it like to be a Cardiac Sonographer?

Duties and responsibilities

A cardiac sonographers is a specialist ultrasound technician. They use ultrasound imaging technologies to aid the diagnosis and treatment of cardiac conditions in patients. Cardiac sonographers do not actually diagnose patients but they play a central role in detecting issues related to blood flow and heart malfunctions and in supporting physicians as they develop diagnoses and design patient treatment plans. Their typical duties and responsibilities include:

  • Conducting medical imaging procedures, such as ultrasounds and echocardiograms to capture images of patients’ hearts and vascular function
  • Evaluating the medial images and deciding which ones to save based on image clarity and other functions
  • Supporting diagnostic procedures by helping physicians to develop a diagnosis
  • Supporting patients, answering their questions and acting as a liaison between patients and doctors
  • Maintaining equipment so that it remains functional and reliable


To become a cardiac sonographer, you will need to achieve an associate’s or bachelors degree in sonography or in cardiovascular and vascular technology. Employers typically prefer graduates of programs accredited by the Commission on Accreditation of Allied Health Education Programs (CAAHEP). Alternatively, one-year certificate programs also are available from colleges and some hospitals.

Cardiovascular and vascular programs include coursework in either invasive or noninvasive cardiovascular or vascular technology procedures. In addition to requiring classroom study, most programs include a clinical component where you will work under a more experienced technologist in a hospital, a physician’s office, or an imaging laboratory.

Most employers prefer to hire cardiac sonographers with a professional certification, or they may expect applicants to earn certification shortly after being hired. Many insurance providers and Medicare pay for procedures only if a certified sonographer, technologist, or technician performed the work. Certification is available from the American Registry for Diagnostic Medical SonographersCardiovascular Credentialing International, and American Registry of Radiologic Technologists.
