  • instructor, electroencephalographic (EEG)
  • technologist, charge - electrocardiography
  • technologist, ECG (electrocardiography)
  • technologist, EEG (electroencephalography)
  • technologist, ENP (electroneurophysiology)


Cardiology technologists perform some or all of the following duties:

  • run electrocardiogram and other electronic equipment to record patient cardiac activity
  • do cardiovascular procedures and tests, such as electrocardiograms, exercise tolerance tests, ambulatory monitoring and scanning of tapes, pacemaker analysis and follow-up, and holter arrhythmia scanning
  • record and assess cardiac activity and provide preliminary reports of tests
  • care for patients during procedures and tests
