The CET certification is a focused, specialized credential that validates your ability to perform 12-lead electrocardiograms, recognize cardiac rhythms, operate cardiovascular monitoring equipment, and support cardiology teams in hospitals, clinics, and cardiac care units across the country.
The Certified EKG Technician (CET) is a nationally recognized credential awarded by the National Healthcareer Association (NHA) that certifies your proficiency in performing electrocardiography – the diagnostic procedure that records the electrical activity of the heart. EKG technicians play a critical role in the diagnosis and monitoring of cardiovascular conditions, one of the leading causes of illness and mortality in the United States.
EKG technicians operate electrocardiograph machines to produce 12-lead EKG tracings that physicians and cardiologists use to identify arrhythmias, detect signs of myocardial infarction (heart attack), evaluate the effects of cardiac medications, assess pacemaker function, and monitor patients at risk for cardiac events. In addition to standard 12-lead EKGs, CET professionals may perform Holter monitoring (continuous 24–48 hour cardiac recording), stress testing (exercise EKG), and telemetry monitoring in hospital settings.
Cardiovascular disease remains the number one cause of death in the United States, and the aging of the population is driving sustained growth in demand for cardiac diagnostic services. This translates to excellent and stable employment prospects for certified EKG technicians across hospital cardiac departments, cardiologist offices, cardiac catheterization laboratories, urgent care centers, and mobile cardiac monitoring companies.
The CET certification is an excellent entry point into the cardiovascular technology specialty. Many CET professionals advance their careers by pursuing additional certifications in echocardiography, cardiovascular technology, or cardiac sonography, building on the strong cardiac anatomy and electrophysiology foundation established by the CET program. For those passionate about cardiac health and a specialty clinical role, the CET certification is an outstanding career investment.
The CET program is ideal for individuals who want a specialized clinical role with a clear focus in cardiovascular care, and who are interested in working with diagnostic technology that has an immediate and meaningful impact on patient health.

Exercise stress test protocols and contraindications, patient preparation and monitoring during stress testing, telemetry monitoring concepts, continuous cardiac surveillance in hospital settings, and recognizing changes requiring immediate intervention.
Patient education for EKG procedures, managing anxious patients, infection control and electrode hygiene, equipment safety, emergency response for cardiac events, CPR awareness, and documentation of EKG procedures in the medical record.
Comprehensive review of all CET exam domains, anatomy and rhythm identification practice, full-length timed practice exams, test-taking strategies, and confidence-building assessments before your NHA CET examination date.
Certified EKG Technicians work in some of the most clinically significant environments in healthcare, where their specialized diagnostic skills directly contribute to life-saving cardiovascular care. The focused, specialized nature of the CET credential makes it highly valued in cardiac care settings.
Many CET professionals use the certification as a foundation for advancement into cardiovascular technology, echocardiography, cardiac catheterization laboratory work, or cardiac nursing. Employers in cardiac care actively seek certified EKG technicians who can perform procedures accurately and independently.
On a typical day, a Certified EKG Technician performs 12-lead electrocardiograms on patients referred by physicians, applies and removes Holter monitors for ambulatory cardiac recording, assists with stress testing procedures, and in hospital settings may monitor telemetry units for arrhythmia detection. EKG technicians prepare patients for procedures, operate EKG equipment, recognize technical artifacts, and transmit completed tracings to cardiologists for interpretation. The work is procedure-focused, patient-facing, and technically rewarding.
No prior cardiac or clinical experience is required. Our CET program begins with cardiovascular anatomy and physiology fundamentals, building the foundational knowledge you need to understand EKG procedures and cardiac rhythms from the ground up. The curriculum is designed to take you from foundational concepts to examination readiness, regardless of your starting point.
EKG technicians work in a variety of clinical settings, including hospital cardiac departments and cardiac care units, cardiologist and internist offices, cardiac catheterization laboratories, cardiac rehabilitation centers, urgent care centers, and mobile cardiac diagnostic companies that perform EKGs at nursing homes, physician offices, and patients' homes. Hospitals are the largest employers of EKG technicians, with opportunities in both inpatient and outpatient cardiac services.
EKG technician salaries vary by location, experience, and work setting. Nationally, CET professionals typically earn between $34,000 and $52,000 annually. Hospital-based positions often include shift differentials for evening, overnight, and weekend work, which can significantly increase total compensation. Experienced EKG technicians who advance to cardiovascular technologist roles with additional credentials earn considerably more.
Absolutely. The CET is widely recognized as an excellent entry point into the cardiovascular specialty. Many CET professionals go on to pursue additional credentials in echocardiography (cardiac ultrasound), cardiovascular technology (CVT), cardiac catheterization laboratory technology, or even advance to nursing with a cardiac specialty. The cardiac anatomy, electrophysiology, and procedural experience gained as a CET provides a strong foundation for these advanced cardiovascular career pathways.
EKG technicians are trained to recognize normal and abnormal cardiac rhythms and to identify technically adequate versus technically inadequate EKG tracings. While formal diagnostic interpretation (making clinical diagnoses) is the responsibility of physicians and cardiologists, CET professionals must be able to recognize life-threatening arrhythmias that require immediate reporting to clinical staff. Our curriculum includes comprehensive rhythm recognition training to prepare you for this critical safety responsibility.
The NHA CET certification is valid for two years from the date of issue. Renewal requires completing 10 continuing education credits before the expiration date. Given the ongoing evolution of cardiovascular diagnostic technology and cardiac care practices, continuing education ensures CET professionals remain current with best practices and advances in the field. Many employers support and fund continuing education for their certified staff.
