Assessment of Heart Flashcards
Myocardium
middle layer of the heart
How much does each beat of the heart pump?
60 mL
Pericardium
protects and covers heart
outermost layer
Mean Arterial Pressure
pressure necessary to maintain perfusion to major organs
Cardiac output
amount of blood pumped from the left ventricle each minute
AV node bpm range
40-60
purkinjie fiber bpm range
less than 40
what influences cardiac output?
strove volume and heart rate
what is preload?
degree of stretching of myocardial fibers
during the filling
What is afterload?
pressure or resistance ventricles must overcome to eject blood
Where is the aortic area located?
right 2nd intercostal space
Where is the Pulmonic area located?
left 2nd intercostal space
Where is Erb’s point located?
left 3rd intercostal space
where is tricuspid point located?
lower left sternal border, 4th intercostal
Where is mitral/apical point located?
left 5th intercostal medial to midclavicular line
what is included in metabolic syndrome?
HTN
hyperglycemia/DM
hyperlipidemia
High weight
What is the conduction pathway thru heart
SA node
AV node
bundle of his right and left
purkinje fibers
contraction
What is the SA node known as?
pacemaker
What is the AV node known as?
gateway
What are some cardiovascular changes with aging?
calcification of valves
conduction time increases
left ventricle size increase and becomes stiff
aorta and other large arteries get thicker
sensitive baroreceptors
Normal range for cholesterol

range for HDL
females: >50
males: >45
range for triglycerides
men: 40-160
