Question Answer
What types of medications should be withheld at least 24 hours prior to exercise or stress testing?
Show Answer
Beta adrenergic blockers (they blunt the heart rate)
What activities should be avoided by a patient getting ready to undergo an exercise or cardiac stress test? (4)
Show Answer
Eating, drinking caffeinated beverages, smoking or strenuously exercising (3 hours prior to the test)
What events during a stress or exercise test would precipitate ending it early? (4)
Show Answer
Peak exercise tolerance is achieved, moderate/severe chest discomfort, significant increase/decrease of BP from baseline, significant ECG changes indicating ischemia
Who is most likely to undergo a 6-minute walk test?
Show Answer
A patient with heart disease or PAD
What is a 6 minute walk test used to determine?
Show Answer
Response to medical interventions or functional capacity for daily activities
Which one measures the P, QRS, and T waves, the echocardiogram or the electrocardiogram?
Show Answer
Electrocardiogram (ECG)
This cardiac test can identify valvular structures and motion, cardiac chamber sizes and contents, ventricular muscle and septal motion and thickness, the pericardial sac, ascending aorta and ejection fraction.
Show Answer
Echocardiogram
_______ is a type of echocardiogram that uses a single ultrasound beam to record the motion of intracardiac structures, wall thickness and chamber size.
Show Answer
M-mode
_________is a type of echocardiogram that sweeps an ultrasound beam in an arc to record spatial relationships among structures in the heart by providing a cross-sectional view.
Show Answer
2-D
What pharmacologic agents are used in patients unable to exercise prior to an echocardiogram to stress the heart?
Show Answer
Dobutamine (Dobutrex) or dipyridamole (Persantine)

______ is used to provide a more precise echocardiography of the heart by eliminating interference from the chest wall and lungs.
Show Answer
Transesophageal Echocardiography (TEE)
What conditions are contraindications for having a TEE performed?
Show Answer
History of esophageal disorders, dysphagia, or radiation therapy to the chest wall
_______ echocardiography uses agents like albumin bubbles or agitated saline to delineate images in patients that are technically difficult. The agents are injected into the cardiac blood pool enhancing reflectivity.
Show Answer
Contrast
______ is test where a small amount of the patient's blood is removed, mixed with small amounts of a radioactive isotope (Cardiolite) and then re-injected. An ECG is used for timing a cardiac cycle to acquire images.
Show Answer
Multigated Acquisition/MUGA or Cardiac Blood Pool Scan
__________ is used to evaluate myocardium at risk for infarction and to determine infarction size. Radioisotopes are injected intravenously and circulation of the material can detect coronary artery blood flow, shunts, motion of the ventricles, EF and the size of heart chambers.
Show Answer
SPECT (Single positron emission computed tomography)
______ uses two isotopes to identify areas of the myocardium that are viable and non-viable. It is expensive to use.
Show Answer
Positive Emission Tomography (PET)
What is myocardial salvage and how is it measured?
Show Answer
Myocardial salvage is the change between an infarct prior to treatment and an infarct after treatment. It is measured using two separate injections of Cardiolite (one before treatment, one after), called a Cardiolite imaging.
What is perfusion testing, like the Cardiolite imaging test and the stress perfusion test, used to look for?
Show Answer
Coronary blood flow changes with increased activity. An abnormality may be seen that wasn't visible in a resting heart.
What drugs are used to mimic the effects of exercise in patients needing a stress perfusion scan who are unable to exert themselves?
Show Answer
Adenocard (Adenosine) or Dipyridamole
What should a patient avoid who is undergoing a pharmacologically induced stress test?
Show Answer
Calcium channel blockers and beta blockers should be withheld 24 hours before the test, and no caffeine or theophylline products 12 hours before the test (they would prevent vasodilation).
Aminophylline (Phyllocontin) is given to a patients to reduce or eliminate adverse side effects (like bronchospasm) to chemical agents given for a _______ test.
Show Answer
Stress
