Cardiac Cycle: One complete cycle = __________________________
One complete cardiac cycle is typically one heartbeat.
One complete cardiac cycle is typically two heartbeats.
One complete cardiac cycle is typically three heartbeats.
One complete cardiac cycle is typically four heartbeats.
As the atriums are filling, the pressure within them is rising. Once the ____________ pressure exceeds the ventricular pressure, the AV Valves (Mitral & Tricuspid) open.
Atrial
Ventricular
Pulmonary
Systemic
Blood flows from ______________ to ______________ pressure.
high to low
low to high
medium to high
medium to low
What is one of the components to Diastole?
Early Rapid Filling
Atrial Systole
Isovolumic Contraction
Isovolumic Relaxation
Atrial Contraction is also known as atrial ________.
kick
beat
pulse
wave
The amount of blood in the ventricles at the end of diastole causes closure of the __________________.
valves
arteries
veins
capillaries
SL Valves act as _______________ valves that only permit blood flow out of the ventricles during systole.
one-way
two-way
pressure
control
Systole is a period of contraction when the ventricles __________ the blood.
eject
absorb
filter
store
Ejection ______ at the apex and proceeds up to the base of the heart.
begins
ends
stops
pauses
During systole, what are the mitral and tricuspid valves doing?
They are open.
They are closed.
They are partially open.
They are malfunctioning.
"Iso"…meaning _______________
AV
Equal
Different
Similar
All ___ valves are closed for a brief moment in Isovolumic Contraction time
AV
SV
3
4
Cardiac Function = The heart’s ability to successfully pump _______________ to the body under all circumstances
oxygenated blood
oxygen
nutrients
hormones
Diastolic function indicates whether end diastolic pressure (aka filling pressure) is normal or __________________.
abnormal
decent
reduced
unchanged
Diastolic Dysfunction = failure of the ventricle to ____________ and allow normal filling.
relax
contract
expand
compress
During systole, chamber sizes concentrically __________.
decrease
increase
remain the same
expand
During diastole, chamber sizes concentrically __________.
increase
decrease
remain the same
fluctuate
Dyskinesis is defined as ____________________.
movement away from the center
a type of skin disorder
an increase in blood pressure
a form of respiratory issue
Starvation of the myocardium is known as ________________.
ischemia
anemia
hypoxia
malnutrition
Semilunar valves open due to ______ pressure in the ventricles
Higher
Lower
Equal
Period of ventricular contraction
systole
diastole
Cardiac function is determined by both systolic and (a) function
Decreased systolic function can cause
chest pain
palpitations
dyspnea
all of the above
(a) function= ventricles ability to relax
Diastolic (a) = failure of the ventricle to relax and allow normal filling
During systole all walls contract toward the center of the LV
true
false
(a) = excessive wall motion
(a) = decreased wall motion
(a) = no wall movement or thickening
(a) = walls are akinetic, but can be restored
(a) = movement away from the center, or in the opposite direction of normal contraction
