There are several career opportunities in medical testing, including the cardiovascular and neurological technology fields. These occupations involves carrying out medical tests that require the use of complex diagnostic equipment to evaluate or diagnose the condition of circulatory and nervous systems of the body.
Careers in diagnostic medical technology include:
An electrocardiography (EKG) technician prepares and applies electrodes to patients to get a recording (called an electrocardiogram) of their heart’s electrical activity. The electrocardiogram is then analyzed by a cardiologist to determine the presence and extent of certain cardiovascular diseases or heart abnormalities. In monitoring an EKG test, the technician may also provide the physician with preliminary information on what they observed on the tracing.
In addition to carrying out non-invasive tests such as EKG and heart ultrasound (echocardiogram), cardiovascular technologists are involved in invasive studies of the heart. They assist cardiologists with introducing various dyes, probes, and catheters into patients’ hearts via entry through blood vessels in the leg or wrist. This is performed to determine whether a coronary blockage exists or for other diagnostic purposes.
CV technologists may also assist cardiothoracic surgeons during angioplasties (balloon procedures performed to open clogged arteries), stenting or implantation of pacemakers under the chest wall to help the heart maintain a normal rhythm.
An electroneurodiagnostic (END) technologist is specially trained in how the nervous system works and many of its disorders. They prepare and perform various tests to measure the electrical activity of the brain and nerves (central and peripheral), such as electroencephalograms (EEGs), polysomnograms, evoked potential and nerve conduction studies.
