Job Description

An EKG tech is responsible for providing diagnostic testing and patient care services. As an EKG tech, you will be responsible for conducting EKG tests, monitoring patients’ vital signs, and providing patient education. You will also be responsible for maintaining equipment and keeping accurate records.


An electrocardiogram (EKG) technologist, also known as a cardiovascular technician or technologist, is a medical professional who performs diagnostic testing on patients. EKG techs use special machines to measure the electrical activity of the heart and assess heart health. They may also be responsible for monitoring cardiac patients during surgeries or other procedures.

EKG techs typically work in hospitals, but may also work in clinics, private practices, or other healthcare settings. They typically work full time, but some may work part time or on call. Many EKG techs are certified by the American Society of EKG Technicians (ASET).

Education and Certification

EKG technicians must complete a training program and earn certification to work in the field. Programs may last from a few weeks to a few months, and are typically found at community colleges, technical schools, and some hospitals.

Most states do not have specific licensing requirements for EKG techs, but certification may be required by some employers. The American Society of Echocardiography (ASE) offers the Registered Cardiac Sonographer (RCS) credential, which requires completion of an accredited sonography program, passing an exam, and completing continuing education requirements.


An EKG tech is a highly skilled position that is in high demand. As an EKG tech, you would be responsible for performing electrocardiograms, which are tests that measure the electrical activity of the heart. Your salary would be based on your experience and education.

Job Outlook

The job outlook for EKG technicians is expected to grow by 10% from 2019-2029, according to the U.S. Bureau of Labor Statistics (BLS). This is faster than the average growth rate for all occupations. The aging baby boomer population is one of the main drivers of this growth, as they are more likely to need the services of an EKG technician.

Career Path

An electrocardiogram or “EKG” is a tracing of the electrical activity of the heart. An EKG tech is a professional who uses special equipment to record these tracings. Because the heart is a muscle, its electrical activity can provide important information about its health and function. EKG techs usually work in hospitals or other healthcare settings, and they may also be known as cardiovascular technicians or diagnostic cardiac sonographers.

Advancement Opportunities

EKG techs who are interested in advancing their careers may choose to become cardiovascular technologists or technicians. Cardiovascular technologists and technicians conduct diagnostic tests on patients with heart and blood vessel disorders. They may also assist physicians during surgical procedures. To become a cardiovascular technologist or technician, one must complete an accredited educational program in cardiovascular technology and earn a credential from the Cardiovascular Credentialing International (CCI).
