Cardiovascular Technology

 

 

Description of the Field of Practice

Cardiovascular Technology is a challenging and rewarding career which demands individual initiative, clinical judgment, and a commitment to ongoing professional growth in the rapidly evolving field of cardiovascular diagnosis and treatment.

The Cardiovascular Technologist is a health care professional who, at the direction of a licensed physician, performs diagnostic tests which are used in the diagnosis, treatment, and serial follow-up of patients with cardiovascular disease. Cardiovascular Technology is a title used to describe three basic areas of expertise: Invasive Cardiology, Noninvasive Cardiology, and Vascular Technology. Through subjective sampling and/or recording, the technologist creates an easily definable foundation of data from which a correct anatomic and physiologic diagnosis may be established for each patient.  The role of the Cardiovascular Technologist includes, but is not limited to one of the following:  

Invasive Cardiology

Invasive Cardiovascular Technologists work in cardiac catheterization laboratories, open heart surgical suites and cardiac research facilities. They assist the Invasive Cardiologycardiologist or cardiac surgeon in performing diagnostic and interventional cardiac catheterization and angiography procedures, measuring cardiovascular parameters such as cardiac output, blood flow velocity, cardiovascular dynamics, cardiac electrophysiology parameters, intracardiac shunt detection, valve flow/valve area determinations, intracardiac pressure measurements, oximetry determination, cineangiocardiography, and the measurement and calculation of cardiac function indices. The technologist assists in all phases of catheterization procedure including insertion of the catheter, operation of various electronic instruments and calculation of hemodynamic data. These data are then used by the physician in confirming diagnosis and designing treatment.

Noninvasive Cardiology 

Noninvasive Cardiovascular Technologists prepare, calibrate and operate medical instrumentation utilized in the Noninvasive laboratory including recording and analyzing noninvasive cardiovascular data from M-Mode, 2-Dimensional and Doppler, transesophageal and stress echocardiograms, electrocardiograms, exercise stress tests and ambulatory ECG monitoring. The echocardiogram combined with Doppler investigation is the most extensive noninvasive examination performed and provides visualization of the structure of the heart and evaluation of the flow dynamics associated with cardiac function. These tests are noninvasive examinations and provide information to the physician on both the anatomic structure and function of the heart.echo student scanning

Vascular Technology

Vascular Technologists use quantitative and qualitative noninvasive techniques to diagnose diseases of the vascular system and assess arterial obstruction in the upper and lower extremities, and the cerebrovascular system. Duplex ultrasonic imaging, impedance outflow plethysmography, strain gauge and pneumoplethysmography, and photoplethysmography techniques are utilized to evaluate venous obstruction or venous reflux. Tests include ultrasonic imaging and flow studies of the arteries and veins to detect problems in patients who are at risk for stroke, arterial occlusion, or venous disease; recording and analyzing diagnostic studies utilizing duplex ultrasonography, color-flow imaging, various forms of plethysmography, and other modalities; and preparing, calibrating, and operating medical instrumentation utilized in the Vascular Laboratory.
