Cardiovascular Technologist

Job Description

Cardiovascular Technologists work in conjunction with physicians to diagnose and treat cardiac and peripheral vascular diseases, or those of that heart and blood vessels, respectively. Cardiovascular Technologists work directly with patients to treat patients who might be suffering from any heart ailments or blood vessel ailments.

Cardiovascular Technologists are responsible for providing assistance with any heart-related procedures that a patient might be undergoing. Cardiovascular Technologists help assist physicians with some common tasks that they might need done from someone else like reviewing some of the doctor and patient documentation based on previous patient-physician interactions, monitoring a patient’s heart rate before, during, and after medical procedures, in addition to scheduling various appointments.

Cardiovascular Technologists will also assist the physician with the monitoring, maintenance, and upkeep of equipment that is used on a daily basis. Cardiovascular Technologists are also in charge of answering any questions that the patient might have regarding their current condition, treatment plans, the medical procedure, and any questions they might have regarding some of the tests that were conducted.

In addition, CTs are responsible for educating the patient about what the results mean based on the tests that were conducted for their heart and vascular condition.

Cardiovascular Technologists are also responsible for perform some very complex medical procedures in an emergency scenario like the assistance of installing a pacemaker, taking emergency calls, using defibrillators, conducting tests to determine and diagnose heart disease, stent implants, and more.

As Cardiovascular Technologists progress throughout their career, their job duties will also change based on their skill and experience level.

Another import part of the normal duties that a Cardiovascular Technologist might have includes using different machines to analyze a patient and their vessels to ensure they are as healthy as they can be.

Cardiovascular Technologists also have the ability to specialize in several different areas of practice which allow them to focus on one aspect of the vascular healthcare procedures that they might be working on. The responsibilities for Cardiovascular Technologists will differ based on whether or not they choose to specialize in a certain area of practice, or whether they choose to provide and assist physicians with a broader range of care.

For instance, in some specialties the Cardiovascular Technologist will be tasked with assisting the patient with different drug administration, the positioning of the patient, cleaning and shaving the patient, or monitoring how the patient responds to certain stimulants.

There are three areas of practice in which cardiovascular technologists may choose to specialize:


This specialty includes technologists that administer echocardiograms (EKGs) and sonograms of the heart. Echocardiography also includes those that perform Holter monitor procedures as well as stress testing. Part of working as a Cardiovascular Technologist who specializes in Echocardiography means that you will have to become an expert in several different devices and uses of echocardiograms. Some of the different uses for echocardiograms include Transthoracic, Stress, Three-Dimensional, Fetal, and Transesophageal.

These tests are designed to make sure that the heart is functioning properly and the images help them identify any problems with the heart like any concerns with the aorta, potentially spot any fluid sacs around the heart, or any blood clots in or around the heart.

These different cardiogram uses help Cardiovascular Technologists and Physicians identify different vascular issues that a patient might be suffering from.

Invasive Cardiology

Invasive Cardiology means using minimally-invasive techniques to open up the patient through surgery to help assist in identifying or treating any structural vascular concerns that a patient might be suffering from.

This specialty focuses on invasive procedures like cardiac catheterization, in which a small tube is threaded through a groin artery to the heart. This procedure is necessary to determine whether or not there's a blockage in the vessels that supply the heart.

The two things that Invasive Cardiology is largely responsible for include stenting and angioplasty.

Vascular Technology

Vascular Technologists and sonographers assist physicians with diagnosing disorders that affect circulation. They update and evaluate the patient's history, check their pulses, evaluate blood flow and pressure, and schedule proper testing. Most tests are performed immediately before or after the patient enters surgery.
