Slide Set 5 Flashcards
Wiggers diagram for AS
Ventricular peak exceeds aortic pressure; should be an increase in LAP
Wiggers diagram for MS
Increase in atrial pressure
Wiggers diagram for AR
Increase in pulse pressure seen on aortic pressure tracing
MS has a tendency to send people into ____ HF
Right
Which arteries are the most likely do get damaged? Why?
Endocardial coronary branches/subendocardial arterial plexus; deeper in the hear
Which arteries are less subject to wall stress
Epicardial CAs
Energy requirements are higher deeper in the heart because
need to cycle the Na/K pumps
Reduced ventricular compliance PV loop will show
an increased preload d/t less compliant ventricle; higher pressures needed to achieve EDV of 120
Preload/filling pressures of ____ put the patient at risk for ______
30 mmHg; right heart failure
Concentric hypertrophy can be caused by? What will this cause eventually?
Chronic HTN; aortic stenosis; diastolic HF
Eccentric hypertrophy is the byproduct of?
Overfiling; Aortic/mitral regurg; ventricular septal defect
Over time, eccentric hypertrophy will cause
Systolic HF
Formula for EF
SV/EDV
Patent ductus artiosus is a problem because
it impairs O2 delivery to CV system
The thyroid controls
metabolic rate
