Cardiovascular technology means the entire cardiovascular system, including the heart and blood vessels, while cardiac technology focuses specifically on the heart and its functions.

Example, Cardiovascular technologists work in cath labs, assist with procedures like stent implants and pacemaker/ICD implantation, and perform tests to diagnose heart disease. Cardiac technologists may work with patients undergoing cardiac procedures, manage cardiac emergencies, and assist in the implantation of devices like pacemakers and defibrillators.
