61

radioactive substances injected into bloodstream used to trace the patterns of blood flow in the heart – assesses the adequacy of blood flow to the cardiac tissues can identify cold spots decreased perfusion

Nuclear Cardiography

62

will give you information about pressures /volume go through the femoral vein and lodge in pulmonary artery can give you information about pressure within rt atrium, CVP, right ventricular pressure, left atrial pressure .

right cardiac catheterization

63

do to evaluate if they have atherosclerotic plaque / blockages in coronary arteries. Would insert femoral artery lodge in coronary sinus and dye is injected.

left cardiac catheterization

64

Who would go for right cardiac catheterization

someone with heart failure

65

When would you do a left cardiac catheterization

someone presents with chest pain and positive enzyme test

66

_____can assess: Cardiomegaly, ventricular hypertrophy, valvular disorders, incompetence, stenosis, collections of fluid can, left ventricular function

echocardiogram

67

Which of the following is the preferred test for measuring ejection fraction?

echocardiogram

68

inability to have sufficient CO to meet the metabolic demands of tissues and organs

CHF

69

PINK FROTHY SPUTUM

PULMONARY EDEMA

70

The sound of excess volume, a ventricular gallop

S3

71

sound of ventricles when blood is trying to enter the stiff noncompliant L ventricle – an atrial gallop, ‘Tennessee’ tachycardia

S4

72

LESS INVASIVE Echocardiogram, will give you info about whether there’s a dissection will give info volume of blood in heart, how much blood loss is occurring, valvular status, info about EF, info about blood clotting in any chambers of heart

TTE

73

you see a widening of the _______ with aortic dissection

mediastinum

74

People with ejection fraction under 30% get a ____

ICD – internal cardioverter defibrillator

75

EF <40% but can walk two flights of stairs or two blocks and does not get SOB,

NYHA Class 1

76

2 flights of stairs, 2 city blocks SOB and have to stop

NYHA Class 2

77

Shaving, combing hair and causing SOB – minimal exertion

NYHA Class 3

78

Dyspnea at rest

NYHA Class 4

79

the patient has S/S of venous congestion, manifested as Edema, fluid can exit to the peritoneal cavity they can have a condition where the abdomen fills up with fluid (ascites), JVD_________

Backwards effects of R heart failure due to congestion of venous system

80

Management is aimed at stopping SNS activation, meds used: ______ to block norepinephrine and epinephrine for stopping systolic heart failure.

beta blockers

81

Identified by EF of 40% or less

systolic dysfunction

82

MI and ischemia common etiologies of __________

systolic dysfunction

83

reduced inotropy during ventricular systole

systolic dysfunction

84

Due to low output state of LV, a sympathetic response b/c tissue is not being perfused will be the release of neurohormone ________ but ultimately this re-arranges the tissue which is termed _________

norepinephrine; ventricular remodeling

85

Heart Failure with preserved ejection fraction “the heart has problem relaxing” a sign of what kind of dysfunction?

Diastolic dysfunction

86

Low cardiac output, congestion, and edema formation with normal ejection fraction. It’s a Lusotropic problem. The ventricles are stiff and don’t relax properly.

Diastolic Dysfunction

87

Explain the 6 box method

let’s say you find a QRS complex that falls directly on a line on an EKG strip, and then you count over, if the next QRS complex occurred at 1, HR would be 300. If the next QRS complex was at 2 HR would be 150 and so on.
