Isovolumetric contraction begins immediately after:
A. the end of the P wave B. the end of the QRS wave C. the end of the T wave D. the onset of the P wave E. the onset of the QRS wave F. the aortic valve closes |
E. the onset of the QRS wave
p. 434 |
|
|
|
True or False:
The peak of aortic flow precedes the peak of ventricular pressure. |
True
p. 434 |
|
|
|
True or False:
The peak of ventricular pressure precedes the peak of aortic flow. |
FALSE. It is the other way around! The peak of aortic flow precedes the peak of ventricular pressure.
p. 434 |
|
|
|
_____ marks the end of rapid ventricular ejection.
A. the end of the P wave B. the end of the QRS wave C. the end of the T wave D. the onset of the P wave E. the onset of the QRS wave F. the onset of the T wave |
F. the onset of the T wave
p. 435 |
|
|
|
In what portion of the cardiac cycle is there a brief negative aortic flow in the Wiggers diagram and what is the explanation for that?
|
At the begining of isovloumetric ventricular relaxation, before complete closure of valves occur, there is a slight retrograde flow of blood that had just been ejected. This accounts for "negative aortic flow" seen on the Wiggers diagram. p. 435
|
|
|
|
In what portion of the cardiac cycle does the dicrotic notch (aka incisura) come about and what is the explanation for that?
|
This occurs in the isovolumetric relaxation phase. Following closure of the aortic valve, aortic pressure increases a second time despite absence of blood flow into the aorta. This is due to elastic recoil of the aortic valve and aorta as well as reflections. p. 435
|
|
|
|
Isovolumetric relaxation occurs after:
A. the end of the P wave B. the end of the QRS wave C. the end of the T wave D. the onset of the P wave E. the onset of the QRS wave F. the onset of the T wave |
C. the end of the T wave
p. 435 |
|
|
|
True or False:
Rapid blood flow into the ventricle and/or rapid relaxation of the muscle sets up vibrations giving the 2nd heart sound, S2. |
FALSE.
This yields the 3rd heart sound, S3. The closing of the semilunar valves (AV slightly before pulmonic) is what yields the 2nd heart sound! p. 436 |
|
|
|
Atrial systole causes the ______ in atrial and central venous pressure traces.
A. A-wave B. C- wave C. V-wave |
A. A-wave
p. 436 |
|
|
|
The _________ marks the end of atrial systole.
A. P-wave B. QRS- wave C. T-wave |
B. QRS- wave
p. 436 |
|
|
|
Regarding venous pressure, the A-wave is caused by...
|
atrial systole
p. 438 |
|
|
|
A second maxima, the __- wave closely follows the A-wave. What accounts for this second maxima?
|
C-wave. Caused by bulging of the tricuspid valve into the right atria due to right ventricular contraction.
p. 438 |
|
|
|
The ____-wave reflects blood flow from the great veins into the right atria.
|
V-wave
p. 438 |
|
|
|
This results from the sudden tension and recoil of the AV valves and adjacent structures.
A. S1 B. S2 C. S3 D. S4 |
A. S1
p. 440 |
|
|
|
These heart sounds can be split due to inspiration.
A. S1 B. S2 C. S3 D. S4 |
A. S1 and B.S2
p. 440 |
|
|
|
This heart sound occurs on closure of the semilunar valves at onset of isovolumetric relaxation.
A. S1 B. S2 C. S3 D. S4 |
B. S2
p. 440 |
|
|
|
This heart sound is caused by vibration of ventricular walls as blood passively flows from atria to ventricle during the rapid phase of ventricular refilling.
A. S1 B. S2 C. S3 D. S4 |
C. S3
p. 441 |
|
|
|
This heart sound is physiologically normal in young individuals but when it returns in older age, it often reflects decreased compliance of the ventricular wall , as in congestive heart failure.
A. S1 B. S2 C. S3 D. S4 |
C. S3
p. 441 |
|
|
|
This heart sound is caused by rapid filling of the ventricle during atrial systole. It occurs at the peak of atrial contraction, immediately before S1. It is always inaudible in normal adults.
A. S1 B. S2 C. S3 D. S4 |
D. S4
