AACVPR CCRP Chapter 10 Exam Questions With Accurate
Answers.
How do you measure a MET? - accurate answers-1 MET = 3.5ml/kg/min of
oxygen consumption
What is ventricular entropy? - accurate answers-> 7 PVCs per minute
How is ejection fraction measured? - accurate answers-measured by
echocardiography or cardiac catheterization
- is calculated by divine stroke volume (SV) by end-diastolic ventricular
function
What is the EF at rest generally between? - accurate answers-50-60%
What is a reduced EF? - accurate answers-<50%
A reduced EF is associated with - accurate answers-left ventricular systolic
dysfunction and my produce signs and symptoms of heart failure
An EF of < or equal to 35% represents - accurate answers-significant left
ventricular dysfunction
What does rate pressure product reflect? - accurate answers-myocardial
demand
- particularly important in patients with myocardial ischemia as signs and
symptoms of ischemia generally occur at a consistent and reproducible RPP
How do you estimate rate pressure product? - accurate answers-RPP= (HR x
SBP)/100
What are normal ECG responses to exercise? - accurate answers-- minor and
insignificant changes in p wave morphology
- superimposition of the p and t waves of successive beats
- increases in septal q wave amplitude
- slight actresses in r wave amplitude
, - increases in t wave amplitude (although wide variability exists among
subjects)
- minimal shortening of the qrs duration
- depression of the j point
- rate relates shortening of the qt interval
What are abnormal ECG responses to exercise? - accurate answers-- st-
segment elevation
- st-segment depression
- st-segment normalization or absence of change
What is st- segment elevation? - accurate answers-early repolarization
1. exercise induced
- displaying a precious q wave infarction my be indicative of a wall motion
abnormality or ventricular aneurysm
On a normal ECG, what does st- segment elevation indicate? - accurate
answers-significant myocardial ischemia
ST- segment elevation indicates what when followed by evolution of
significant q waves - accurate answers-myocardial injury
What is the most common manifestation of exercise induced myocardial
ischemia? - accurate answers-ST segment depression
Does ST- segment depression localize ischemia to a specific area of
myocardium? - accurate answers-no
What is a positive test for ST- segment depression? - accurate answers-> or
equal to 1.0mm of horizontal or down sloping ST segment 80 msec after j
point
ST- depression: the more leads with ischemic shifts, - accurate answers-the
more severe the disease
Signifies ST-segment depression occurring only in recovery represents -
accurate answers-a true positive response
