Cardiac Diagnostics
Standard
25) Research the educational requirements, certification, and licensures for cardiovascular technologist, diagnostic vascular technologist, electrocardiogram technician, telemetry technician, cardiac sonographers, and other related cardiovascular careers. Compare and contrast the educational requirements of each.
26. Investigate cardiac diagnostic procedures both in-hospital and out-patient and identify the equipment required for these services.
Objectives
Differentiate the eight common
cardiac diagnostic procedures
Compare/contrast various cardiac
careers
Cardiac Diagnostic Tests
1. Electrocardiogram (ECG/EKG)
2. Stress test ( also called treadmill or exercise ECG)
3. Holter monitor
4. Cardiac catheterization (also called coronary angiogram).
5. Echocardiogram (also known as echo)
6. Transesophageal echocardiogram (TEE)
7. Positron emission tomography (PET) scan
8. Magnetic resonance imaging (MRI) of the heart
Diagnostic Tests
Electrocardiogram (ECG/EKG). This test records the electrical activity of the
heart, shows abnormal rhythms (arrhythmias), and can sometimes detect
heart muscle damage.
Stress test ( also called treadmill or exercise ECG). This test is done to monitor
the heart while you walk on a treadmill or pedal a stationary bike. Your
doctor also monitors your breathing and blood pressure.
used to detect coronary artery disease, or to determine safe levels of
exercise after a heart attack or heart surgery.
This test can also be done using special medicines that stress the heart in
a similar manner as exercise does.

Stress Test
Diagnostic Tests
Holter monitor. For this test, you wear a small, portable, battery-powered ECG machine to record heartbeats over a period of 24 to 48 hours during normal activities. At the end of the time period, you will return the monitor to the doctor's office so it can be read and evaluated.
Cardiac catheterization (also called coronary angiogram). For this test, your doctor guides a small catheter (hollow tube) through the large artery in your upper leg, or sometimes your wrist or arm, into your heart.
Dye is given through the catheter, and moving X-ray pictures are made as the dye travels through your heart.
This comprehensive test shows: narrowing in the arteries, heart chamber size, how well your heart pumps, and how well the valves open and close, as well as a measurement of the pressures within the heart chambers and arteries.

Diagnostic Tests
Echocardiogram (also known as echo). An echo is a noninvasive test that
uses sound waves to evaluate your heart's chambers and valves, as well
as its pumping function. The echo sound waves create an image on the
monitor as an ultrasound probe is passed across the skin over your heart.
Transesophageal echocardiogram (TEE). In this test, you will swallow a
small probe, about the size of a little finger. The probe passes down the
esophagus nearer to the heart. It allows a closer look at the heart's
structure and function. It also shows any abnormal tissue around your
heart valves, if blood is leaking backward through a valve, and if blood
clots are present in your heart chambers.

Diagnostic Tests
Positron emission tomography (PET) scan. This is a nuclear scan that gives information about the flow of blood through the coronary arteries to the heart muscle
Magnetic resonance imaging (MRI) of the heart. This procedure uses a combination of large magnets, radiofrequencies, and a computer to make detailed images of organs and structures in your body.
evaluate the heart valves and major vessels, detect coronary artery disease, and the extent of damage it has caused
evaluate congenital defects, and detect the presence of tumors or other abnormalities.
do this test before other procedures such as angioplasty or stenting of the coronary arteries and heart or vascular surgery:
