A CCT (Certified Cardiographic Technician) job involves performing diagnostic tests to monitor patients' heart activities, such as electrocardiograms (EKGs), stress tests, and Holter monitoring. CCTs work in hospitals, clinics, and cardiology offices, assisting doctors in diagnosing cardiovascular conditions. They must have strong attention to detail, knowledge of medical equipment, and patient care skills. Certification from a recognized organization, such as CCI (Cardiovascular Credentialing International), is often required to work as a CCT.
