To become a cardiovascular technologist you typically need an associate's degree or a postsecondary certificate in cardiovascular technology, with clinical training built in, and many employers want professional certification plus basic life support or CPR. If you want a faster start, BLS says EKG technicians may qualify for entry-level jobs with a high school diploma, and EKG certificate programs usually take under a year.
Cardiovascular technologists and technicians run tests and help with procedures involving the heart and lungs. The job covers a wide range, from attaching EKG leads in a clinic to assisting a cardiologist during a catheterization.
Everything here comes from the US Bureau of Labor Statistics (BLS) Occupational Outlook Handbook profile for cardiovascular technologists and technicians, read as of October 2026. It's a careers guide, not medical advice.
Cardiovascular tech jobs and pay at a glance
| Measure | BLS figure |
|---|---|
| Typical entry education | Associate's degree |
| Median pay (May 2025) | $74,310 a year, or $35.73 an hour |
| Lowest 10% earned less than | $39,000 |
| Highest 10% earned more than | $121,350 |
| Jobs in 2025 | 64,500 |
| Projected growth, 2025 to 2035 | 4%, about as fast as average |
| Openings each year | About 3,400 |
These are BLS figures as published as of October 2026. Pay varies with your specialty, your setting and the shifts you work.
Three jobs under one title
BLS describes several types, and choosing one shapes your training:
- Cardiovascular invasive specialists, also called cardiac catheterization technologists, help physicians as a catheter is threaded through an artery to the heart. They also prepare and monitor patients during open-heart surgery and during insertion of pacemakers, defibrillators and stents.
- EKG technicians specialize in electrocardiogram testing, attaching electrodes to a patient's chest, arms and legs to record how the heart performs at rest or during activity.
- Other technologists may focus on a particular kind of test or help with specific procedures.
If heart imaging with ultrasound appeals more, that's a sonography specialty. My guide on how to become a sonographer covers that route.
The route in, step by step
- Take science at school. BLS suggests anatomy, physiology, physics and math for high school students interested in this field.
- Pick your entry point. Go straight for an associate's degree or certificate in cardiovascular technology, or start as an EKG technician with a high school diploma and a short certificate.
- Complete clinical training. Programs usually include courses in anatomy, medical terminology and applied sciences, plus a clinical component where you earn credit working under an experienced worker.
- Get certified. Employers may require or prefer professional certification, and you may also need basic life support or CPR certification.
- Check your state. BLS says some cardiovascular technologists and technicians need a state-issued license.
Why the EKG route is worth a look
Most people assume they need two years of college before they can work in cardiology. BLS says otherwise for EKG work: a high school diploma may be enough for an entry-level job, and certificate programs usually finish in under a year. Starting as an EKG technician lets you earn while you decide whether the invasive side is for you.
Where the pay is higher
In May 2025 BLS reported these medians by industry:
| Industry | Median pay (May 2025) |
|---|---|
| Outpatient care centers | $95,080 |
| Medical and diagnostic laboratories | $81,200 |
| Offices of physicians | $76,850 |
| Hospitals; state, local and private | $69,970 |
Hospitals employ 77% of cardiovascular technologists and technicians, but they pay the least of those four settings. Outpatient care centers employ far fewer people and pay more, which is worth knowing once you have experience.
What the job is like
You'll work in healthcare settings, mostly hospitals and physicians' offices. You may stand for long periods and need to lift or turn patients who are ill or disabled. Because many facilities never close, shifts can include evenings, weekends or overnights, and part-time work is common.
You'll work closely with heart doctors. If you're curious about the physician side, my guide on how to become a cardiologist explains that much longer path.

Choosing a cardiovascular technology program
Because training mixes classroom and clinical work, the clinical side is where programs differ most. Before you enrol, ask where students do their clinical placements, which kinds of procedures they'll see, and whether the program prepares you for the certification employers in your area ask for.
- Does the course cover anatomy, medical terminology and applied sciences, as BLS describes?
- Will you earn credit working under an experienced worker in a hospital or physician's office?
- Does it lead to an associate's degree or a certificate, and which suits the jobs you want?
- Will you leave with basic life support or CPR certification?
It's also worth asking local hospitals what they look for. Hospitals employ 77% of people in this field, so their hiring preferences matter more than any brochure.
One more practical point: BLS notes that most people in this field work full time, but part-time work is common. If you're studying or caring for family, an EKG technician role with part-time shifts can be a realistic way to get experience while you train for the next step.
Finally, think about which patients you want to work with. EKG testing often happens in clinics and physicians' offices, while invasive work takes place around procedures and surgery. Shadowing in both settings, if a program offers it, will tell you a lot about where you'll be happiest.
My verdict
If you want a hands-on heart career without medical school, this is a strong option. Start as an EKG technician if you need to work sooner, or go straight for an associate's degree or certificate if you're aiming at invasive work. Get certified, keep your CPR current, and consider outpatient settings once you've built experience.
Frequently asked questions
How long does it take to become a cardiovascular technologist?
Most cardiovascular technologists need an associate's degree or a postsecondary certificate. EKG technicians can start faster: BLS says EKG certificate programs are generally completed in under a year.
Do you need certification?
Employers may require or prefer professional certification, and you may also need basic life support or CPR certification. Some states require a license.
How much do cardiovascular technologists make?
BLS reported a median of $74,310 a year in May 2025, as of October 2026. The highest 10% earned more than $121,350.
What's the difference between an EKG technician and a cardiovascular technologist?
EKG technicians specialize in electrocardiogram testing and may start with a high school diploma. Cardiovascular technologists, such as invasive specialists, usually need more training and assist with procedures like cardiac catheterization.
