A cardiovascular technologist runs the tests that show how a patient's heart and blood vessels are working: EKGs, stress tests, Holter monitors, echocardiograms, and (in the cath lab) assisting the physician during catheterizations. You are the physician's eyes and hands, and you are also the calm voice that helps a nervous patient. Most people enter through a 2-year associate degree or a 1-2 year certificate program with clinical rotations, then earn a credential such as CCT, RCS, RCIS, or RDCS. Start with anatomy and EKG rhythm reading, because everything else builds on them. Then learn pati

Stage 1 of 4 · about 14 weeks
Learn heart anatomy, blood flow, basic physiology, medical terminology, and how to read a normal EKG. Finish prerequisites for a CAAHEP-accredited program and earn BLS. Shadow or volunteer in a hospital if you can.
Medical Terminology
Every order, chart note, and physician instruction you will handle uses this language. If you can break a word apart, you can understand words you have never seen, and you will document safely and accurately.
Heart Anatomy and Blood Flow
You will place electrodes, position patients for echo views, and later scan or assist in the cath lab. You can only do that well if you picture the heart in 3D and know where blood goes. This is the map for everything else in your career.
Cardiac Physiology and the Electrical Conduction System
The EKG is a picture of the heart's electricity. If you understand how the heart is triggered and why it squeezes, then waves on a tracing become a story instead of squiggles to memorize. It also helps you notice when a patient looks unwell while the machine says otherwise.
Reading a Normal EKG
Before you can spot a dangerous rhythm, you must know exactly what normal looks like. Most of your first weeks on the job will be recording clean normal tracings and knowing quickly when something is off so you can alert the physician.
BLS Certification, Prerequisites, and Hospital Exposure
Hospitals and CAAHEP-accredited programs require current BLS. Programs also have competitive prerequisites, and real exposure to a clinical setting confirms this job is right for you and strengthens your application.
