CCT Test Questions and 100% Correct
Verified Answers
Persantine Chemical Stress Test - Answer -aka dipyridamole
-anti-platelet agent that dilates the coronary blood vessels
-side effects: abd upset, arrhythmias, dizziness, headache, CP, low BP, rarely a heart
attack or stroke
-aminophylline reverses the side effects
Negative Stress Test - Answer -no abnormalities seen in the J-point or ST segment
-pt achieves at least 85% of max HR
-pt's have a low likelihood of developing CV disease or experiencing myocardial ischemia
or inury
Thallium Stress Test - Answer -useful in determining the extent of preexisting damage or
blockage due to the heart, effectiveness of CV therapies, or cause of CP
-mixes with all the blood; the higher amt of blood in a region, more of the chemical can
be seen
-if an area of the heart does not get enough blood flow, only a small amt of chemical will
be seen
-the presence or absence of the chemical is a useful indicator of limited blood flow or
dead muscle cells in the heart
-side effects are rare but include: rash and low BP
Arm Ergometer Stress test - Answer -seated with handles of ergometer positioned at
chest level
-pt's must maintain 60-75 revolutions per minute
-less sensitive than leg exercise in determining CV abnormalities
, SA block - Answer This is the inability of an electrical impulse to be generated by the SA
node causing no P wave to be seen. May occur intermittently and cause the pt no
problem or symptoms.
Wolf-Parkinson-White syndrome aka: pre-excitation syndrome - Answer - electrical
impulse from the atria reaches the
ventricle too soon
- An extra pathway is present that conducts electrical impulses from the atria to the
ventricles.
- short PR, delta wave, BBB, and tachyarrhythmia
- Symptoms: rapid HR, dizziness, CP, fainting
Myocardial Ischemia - Answer Inverted T waves and ST depression can
indicate_____________?
Myocardial Ischemia - Answer - LT ventricle does not receive enough
oxygenated blood due to an obstruction or
constriction of blood vessels
- Caused by atherosclerosis
- reversible if diagnosed early
- Prolonged ischemia = injury or infarction
Heart Block - Answer - abnormality in the electrical conduction system of the heart that
disrupts the propagation of electrical impulses through the AV node.
- a decreased spread of electrical impulses leads to a decreased HR
- Symptoms: fainting, dizziness, SOB, CP
