Q

Beck’s Triad

A
  1. Increased pressure outside the heart decreases end-diastolic ventricular filling
  2. Increased pressure reduces end-systolic atrial filling capacity
  3. Increased fluid: reduced heart sounds

54
Q

Resting Tension in the heart

A

Force required to stretch a resting muscle to different lengths

55
Q

Active Tension in the heart

A

When a muscle is stimulated to contract whilst its length is held constant, it develops an additional force called active tension

56
Q

The peak isometric tension in the heart

A

The total tension developed (active and passive). This depends on the initial myocardial muscle length.

57
Q

Norepinephrine increases the [ ] of the cardiac muscle

A

Contractility

58
Q

Contractility

A

How efficiently the myocardium contracts from a given myocardial muscle length.

59
Q

When afterload is large, does shortening of the cardiac muscle occur?

A

NO

60
Q

The [ smaller or larger ] the afterload the faster the shortening velocity

A

Smaller

61
Q

Changes in myocardial muscle fiber length is:

A

The Preload

62
Q

The forces the muscle must overcome to open the valves and to eject a given volume of blood

A

Afterload

63
Q

The contractile ability of the heart

A

Inotropic state

64
Q

Starling’s Law of the heart states that:

A

As EDV increases, the stroke volume increases

65
Q

Cardiac defects associated with 22q11 deletions (DiGeorge’s)

A

Truncus arteriosus and Tetralogy of Fallot

66
Q

Cardiac defects associated with down syndrome

A

VSD, ASD, AV septal defect (endocardial cushion defect)

67
Q

Cardiac defects associated with Turner syndrome

A

Coarctation of the aorta

68
Q

Cardiac defects associated with offspring of diabetic mother

A

Transposition of the great vessels

69
Q

Cardiac defects associated with congenital rubella

A

Septal defects, PDA, pulmonary artery stenosis

70
Q

Cardiac defects associated with Marfan Syndrome

A

Aortic insufficiency (late complication)

71
Q

The Myogenic Response

A

Responsible for autoregulation of blood flow. Stretch of blood vessel wall by increasing pressure causes contraction of the smooth muscle of resistance arterioles. A decrease in radius increases Resistance to keep the blood flow constant.
