Cardiac Basics Med Surg 2
test questions and answers
Blood flow through heart
SVC --> R. atria --> Tricuspid --> R. ventricle --> Pulmonic valve -->
Lungs --> L. atria --> Mitral valve --> L. ventricle --> aortic valve -->
aorta --> Body
Heart is 3 systems in 1...
circulatory
conduction
coronary
Systolic
Contraction/ depolarization
Diastolic
Rest/ repolarization
Preload
What's in heart before pump "end-diastolic volume"
Afterload
Force or resistance against which the heart pumps "vascular
resistance"
Pumping out bad SV
body not being perfused
Stroke Volume (SV)
The amount of blood pumped out of the heart with each contraction.
Tachycardia and filling time
less filling time= less blood in ventricles= not a lot being pumped
How is pt. tolerating rhythm?
Assess BP, LOC, color, cap refill, etc.
