Definition

Cardiology technologists operate electrocardiogram equipment and use medical imaging technologies to record cardiac activity of patients to aid in the diagnosis, monitoring and treatment of heart disease. Electrophysiological diagnostic technologists operate electroencephalographic, electromyographic and other electrophysiological diagnostic equipment to assist physicians in diagnosing diseases, injuries and abnormalities. Cardiology technologists and electrophysiological diagnostic technologists who are supervisors or instructors are included in this unit group. They are employed in clinics, hospitals and medical laboratories.

Main duties

Overview

Under the National Occupational Classification (NOC) 2021, cardiology technologists and electrophysiological diagnostic technologists fall under NOC code 32123. These professionals operate electrocardiograms, Holter monitors, cardiac stress testing equipment, electroencephalographs, and other specialized medical diagnostic gear to record cardiac and brain activity. Classified under TEER Category 3, this occupation plays a vital role in Canadian healthcare facilities, including hospitals, clinics, and research laboratories.

To qualify for employment in Canada under NOC 32123, candidates typically must complete a two-year college diploma program in cardiology technology or electrophysiology technology. Employers and provincial regulatory bodies may require registration with professional associations, such as the Canadian Association of Cardio-Pulmonary Technologists (CACPT) or the Canadian Board of Registration of Electroencephalograph Technologists (CBRET). Meeting these credential and licensing standards is critical for both employment and immigration assessment.

Because NOC 32123 is a TEER 3 occupation, skilled workers in this field are eligible for Canada's Express Entry system through the Federal Skilled Worker (FSW) program and the Canadian Experience Class (CEC). Additionally, applicants may benefit from targeted Provincial Nominee Program (PNP) draws and federal category-based selection rounds focused on healthcare occupations.
