1. Cardiac anatomy
by xayouluma

10. Pericardial Tamponade
• Bleeding into
pericardial space
after chest trauma
• Excess blood
restricts expansion
of heart during
pumping
• Causes shock or
death if not
corrected

11. Heart Chambers
Four chambers:
• 2 atria: top of
heart – receive
blood from
veins
• 2 ventricles:
bottom of heart
– pump blood
through arteries

21. Nodes (you need to know these)

22. Valve Disorders
• Leaky Valves:
caused by
incompetent or
deformed valves
that force the heart
to re-pump blood
because of
backflow

23. Stenosis
Valves are stiff and do not open completely.
Heart has to pump harder
Murmur: stenosis

24. Mitral Valve Prolapse• The most
common valve
disorder
(5-10% of people)
• Mitral valve
opens
(prolapses)
into atrium
when shutting
& allows blood
backflow
