Q

Describe the flow of blood from outside the heart, through the heart, and out of the heart.

A

DEOXYGENATED Blood comes from the head and lower body through the superior/inferior vena cave.
It then rushes into the relaxed right atrium, through the tricuspid valves down to the right ventricle.
Then gets pumped through the pulmonic valve to the pulmonary artery which carries it to the lungs to become oxygenated.
OXYGENATED blood then returned through the pulmonary vein to the left atrium, down the mitral valve to the lower left ventricle.
It then is pumped out the aortic valve to the aorta.
Fresh blood is then carried to the head and the rest of the body.

Q

What test shows the conductivity of the heart?

A

Electrocardiogram - ECG

44
Q

What node is known for being the pacemaker of the heart?

A

Sinoatrial (SA) node (60/100bmp)

Note* The SA node consists of a cluster of cells that are situated in the upper part of the wall of the right atrium (the right upper chamber of the heart). The electrical impulses are generated there which regulate the heart beat.

45
Q

What is the proper name for the AV node?

A

Atrioventricular (AV) node (40-60bpm)

Note* The AV node delays cardiac impulses. It ensures that the atria have ejected their blood into the ventricles first before the ventricles contract.

46
Q

What is the T wave in an ECG reading

A

Repolarization of ventricles

47
Q

What is a Q-T interval in an ECG?

A

Ventricular contractions

48
Q

A

Ventricular depolarization

49
Q

in an ECG, what is a P-R interval?

A

Arterial contraction

50
Q

What is a P wave in an ECG reading?

A

Arterial depolarization

51
Q

What is the following equation for?

CO=HRxSV

A

Pumping ability of the heart.
CO= Cardiac output
HR= Heart rate
SV= Stroke Volume

52
Q

What is preload mean?

A

Preload is the venous return that builds during diastole. It is the length to which the ventricular muscle is stretched at the end of diastole just before contraction. When the volume of blood returned to the ventricles is increased (as when exercise stimulates skeletal muscles to contract and force more blood back to the heart), the muscle bundles are stretched beyond their normal resting state to accommodate it. The force for this switch is the preload.
(Think of the balloon already filled with air)

53
Q

What does afterload mean?

A

Afterload is the opposing pressure the ventricle must generate to open aortic valve against the higher aortic pressure. It is the resistance against which the ventricle must pump its blood. Once the ventricle is filled with blood, the ventricular end diastolic pressure is 5 - 10 mm Hg, whereas that in the aorta is 70 - 80 mm Hg. To overcome this difference, the ventricular muscle tenses. After the aortic valve opens, rapid ejections occur.
(Think of your fingers holding air in the balloon)

85
Q

Size: normally 1 x 2 cm

86

Barrell chest

87
Q

Explain the physiologic mechanism for normal splitting of S2. In what location on the heart would you expect to hear a split S2?

A

Splitting of the S2 can happen during inspiration. It is heard when the aortic valve closes earlier than the pulmonic valve. Instead of it sounding like “dub” it sounds like “T-Dub”. You can hear it only in the pulmonic valve area.

88
Q

Explain the position of the valves during each phase of the cardiac cycle.

A

Diastole- AV valves (i.e. tricuspid and mitral) are open
Systole- AV valves shut producing S1.
Aortic valves open to eject blood rapidly. then some back flow from psi equalizing b/t aorta and ventricles causes aortic valve to shut
Diastole again- all 4 valves closed, mitral valve opens and diastolic filling begins again
