Pericardial Tamponade
• Bleeding into pericardial space after chest trauma
• Excess blood restricts expansion of heart during pumping
• Causes shock or death if not corrected
Heart Chambers
Four chambers:
• 2 atria: top of heart – receive blood from veins
• 2 ventricles: bottom of heart – pump blood through arteries
Nodes (you need to know these)
Valve Disorders
• Leaky Valves: caused by incompetent or deformed valves that force the heart to re-pump blood because of backflow
Stenosis Valves are stiff and do not open completely.
Heart has to pump harder
Murmur: stenosis
Mitral Valve Prolapse• The most common valve disorder
(5-10% of people)
• Mitral valve opens (prolapses) into atrium when shutting & allows blood backflow
