Drag and drop the appropriate labels into position to explain how this defect might cause mr. g's other problems.
marissa [1.9K]

How does Mr. G's altered blood flow explain his signs and symptoms? Drag and drop the appropriate labels into position to explain how this defect might cause Mr. G's other problems. Fill the boxes in order, starting with 1, then 2, etc

(Image attached)

Answer:

  1. When left ventricles contracts, some blood goes up through mitral valve into the left atrium, Turbulent flow through the valve causes systolic murmur. the atrium is overfilled and dilated.
  2. Because some blood re-entered the mitral valve, less is pumped out into the aorta. the ejection fraction is only 43%
  3. Less blood enters aorta, so SBP is low. Baroreceptor reflex causes increased heart rate; wall of overworked left ventricles becomes thicker
  4. Because its already partly full of blood from the ventricle, the left atrium accepts less blood from the lungs, the lungs overfilled with fluid; resulting in troubled breathing.

Explanation:

A murmur is a result from a abnormal blood flow to the heart.Its basically an unusual sounds that is heard between heartbeat A systolic murmur occurs when the heart muscles contracts. i.e they begin and end between S1 and S2.

From the above information, it seems like Mr G is experiencing mitral regurgitation. It is a condition where mitral valve doesnt close tightly and as a result the blood flows back from the left ventricle into the left atrium.
