Cardio - General Flashcards
(325 cards)
mitral valve prolapse =
Associated w/
mid systolic click
Marfan’s Syndrome
Cardiac output formula
CO=CVxHR
Total peripheral resistance formula
(MAP - R. Arterial pressure ~0)/CO
Resistance formula
R= ∆P/Q
or ∆P=QR
Resistance in series
R total = sum of Rs
Resistance in parallel
1/R total = sum of 1/R
1st line CHF Rx
ACE inhibitor - prevent cardiac remodeling
-Also beta blockers and ARBs
Loop diuretics is symptom management and HF
CO=
flicks equation
oxygen consumption/( arterial O2 content - venous O2 content)
watch units!!
what divides the R and L embryological atrium? (2)
septum primum -> osteum/foramen secundum
Septum secundom -> foramen ovale
How is blood shunted from the R to L atrium in embryo
foramen ovale (in septum secundum ) and osteum secundum (in the septum primum)
3 possible causes of atrial septal defect?
Common genetic abnormality associated>
osteum secundum overlaps foramen secundum
Absence of septum secundum
neither septum secundum nor septum primum develop
Downs syndrome
6 different aorticopulmonary septal(spiral septal) defects
embryological determination
tetralogy of fallout
persisitant truncus aretiosus
transposition of the great vessels
Dextrocardia
VSD
fenestrae
Neural crest derived
Ascending aorta and pulmonary trunk derived from?
