The median pay is about $74,310 a year. Across everyone in the job it runs from about $39,000 at the lower end to about $121,350 at the upper end. The source is listed under Sources at the end of this page.
2 to 4 years after high school, on the usual route.
$9,000 to $50,000 all in for tuition, fees, exams and kit. Living costs are not counted.
It depends where you work. You need a license, certificate or registration in North Dakota, New Hampshire, New Mexico and Oregon. Elsewhere there is none to hold, though many employers still ask for training or a certificate.

Top tenth
$121,350
The national median is $74,310 a year, the bottom tenth earn $39,000 or less and the top tenth $121,350 or more (2025 federal wage survey). The survey counts two very different jobs together: technicians who run basic heart tracings, and specialists who assist doctors during catheter procedures.
$39,000 to $47,890
The bottom tenth and bottom quarter of cardiovascular technologists and technicians, 2025
New graduates usually start in the lower part of the range. Call pay and shift differentials are added on top of the base rate.
$113,510 a year
The median in Utah, the highest of any state
Hawaii ($111,730) and Massachusetts ($105,580) come next. Mississippi is the lowest, at $38,000. Labs that handle emergency heart attacks need staff available overnight, and call pay is added on top of the base rate.
Roughly, all in
$9,000 to $50,000
Tuition, fees, exams and kit. Not rent, food or travel
The low end is a two year associate degree at an in state community college at about $4,000 a year, plus the credential exams and the scrubs, immunizations and background check every clinical placement demands. The high end is the four year bachelor's route at an in state public university at $10,000 to $12,000 a year with the same exams on top. Filing the FAFSA (Free Application for Federal Student Aid) can knock the community college bill down to almost nothing, and plenty of hospitals pay the tuition for staff already working there who want to move into this role.
File the FAFSA (Free Application for Federal Student Aid). A Pell Grant can cover most of a community college bill, and many hospitals pay tuition for staff who want to move into this role from another job.
Full hospital benefits
Health, dental and a retirement plan from the start, because your employer is usually a large hospital system.
Shift differentials
Extra hourly pay for evenings, nights and weekends.
Call pay
Money for carrying the pager, plus a higher rate when you actually get called in.
Tuition help
Hospitals often pay for staff to add credentials or finish a bachelor's degree.
Portability
Credentials are national, so the job moves with you between states.
The exact path from high school to qualified.
A short, cheap health program with real hospital pay at the end of it.
High school diploma
Grade 12
Biology, anatomy and math. Volunteering at a hospital helps you get into a program.
Get into an accredited program
Apply in Grade 12
Look for cardiovascular technology programs accredited by the Commission on Accreditation of Allied Health Education Programs. Accreditation is what makes you eligible for the credential exams.
Classroom and lab
1 to 2 years
Anatomy, heart physiology, radiation safety, equipment and patient care. You pick a track: invasive, echocardiography or heart rhythm.
Clinical rotations
During the program
Unpaid hours in a real hospital lab, scanning and assisting under supervision. This is where you actually learn the job.
Credential exam and first job
After graduation
Sit the exam for your track, then apply. Many students are hired by the hospital where they did their rotation.
Biology and anatomy
You need to know the heart and its vessels cold.
Physics
Ultrasound and x-ray imaging are both physics, and the programs teach them that way.
Math
Measurements, dosing and calculations during procedures.
English
You explain procedures to frightened patients all day.
46 states and DC (the District of Columbia) do not license this job. What employers require instead is a national credential, earned by graduating from an accredited program and passing an exam. Cardiovascular Credentialing International awards the credentials for invasive, rhythm and cardiac sonography work, and the American Registry for Diagnostic Medical Sonography awards sonography credentials including adult echocardiography. New Hampshire, New Mexico, North Dakota and Oregon license sonographers, and that includes heart ultrasound, so in those four states you need a license to do it.
Invasive
The catheterization lab. You assist doctors threading catheters into the heart, monitor the patient and handle equipment during the procedure.
Echocardiography
Ultrasound scans of the heart. No needles, no radiation, a lot of image interpretation. Often called a cardiac sonographer.
Electrophysiology
The heart's electrical system: mapping rhythms, assisting with ablations, pacemakers and defibrillators.
Vascular
A neighboring specialty scanning arteries and veins elsewhere in the body, with its own credential.
Things you don't need, but that help.
RCIS (Registered Cardiovascular Invasive Specialist)
The catheterization lab credential from Cardiovascular Credentialing International.
RCES (Registered Cardiac Electrophysiology Specialist)
For heart rhythm lab work. A smaller niche.
RCS (Registered Cardiac Sonographer)
The echocardiography credential. Many people hold this plus one other.
RDCS (Registered Diagnostic Cardiac Sonographer)
The adult echocardiography credential from the sonography registry, widely asked for in job postings.
CCT (Certified Cardiographic Technician)
The entry-level tracing and monitoring credential, often a first step while you study for more.
CPR and advanced life support certification
Required by most labs and cheap to get.
Hospital volunteering or a patient care job
Programs prefer applicants who have already been around sick people.
Stamina
You stand for hours in a lead apron, and scanning is hard on shoulders and wrists.
Steadiness under pressure
When a heart attack patient arrives at 2am, the room moves fast and you are part of it.
Travel contracts place you in a hospital for 13 weeks at a time, and plenty of technologists do a few years of that early on. Inside a hospital the ladder runs to lead technologist and then lab manager. Outside it, device companies hire experienced staff to support pacemakers and heart pumps in the field, which involves a lot of driving. Some people use the credential as a stepping stone and go back for nursing or a physician assistant program.
Day to day, pros and cons, where you'd work.
Start at 7am, check the day's schedule and set up the room. In the catheterization lab that means prepping the table, the monitoring equipment and the sterile field, then gowning up in lead. Cases run through the morning: you watch the pressures and rhythms on screen, hand the doctor what is needed, and talk the patient through what is happening. In the echocardiography lab it is quieter, five or six scans a day, each one 30 to 45 minutes of careful imaging. Then reports, cleaning and restocking.
The good
The hard parts
Things people don't tell you.
An EKG (electrocardiogram) takes only a few minutes: ten stickers on the chest and limbs, and a printout of the heart's electrical activity. It is the first test almost every chest pain patient in the country gets.
Catheterization uses live x-ray imaging, so everyone in the room wears a lead apron, a thyroid collar and a radiation monitoring badge that is checked regularly.
O*NET OnLine (the Department of Labor's occupation database) counted about 64,500 cardiovascular technologists and technicians in 2025. It projects average growth to 2035, with about 3,400 jobs opening each year.
Scanning the heart uses the same sound-wave technology as a pregnancy scan. It shows the valves opening and closing and blood moving in color, live on screen, with nothing entering the body.
