Heart failure is the inability of the heart to function well to meet the needs of the body. When the heart is not able to pump out enough blood it is known as heart failure with reduced ejection fraction. Ejection fraction is the fraction of the blood ejected out from the filled heart. The lower chambers of the heart fill when they relax after a contraction.
Content
0.48 -> heart failure is the inability of the
2.159 -> heart to function well to meet the needs
4.72 -> of the body
6.08 -> when the heart is not able to pump
7.919 -> enough blood
9.2 -> it is known as heart failure with
11.44 -> reduced ejection fraction
14.08 -> ejection fraction is the fraction of the
16.08 -> blood ejected out from the filled heart
19.52 -> the lower chambers of the heart feel
21.84 -> when they relax after a contraction as
24.8 -> an example if left ventricle the lower
27.76 -> left chamber has 100 ml of blood after
31.119 -> filling and 35 ml is ejected out during
34.64 -> the next contraction
36.32 -> the ejection fraction is 35
40.239 -> normal ejection fraction of the left
41.84 -> ventricle is above 50 percent
45.12 -> in heart failure with reduced rejection
47.28 -> fraction
48.239 -> the ejection fraction is below 40
50.64 -> percent
51.92 -> when the left ventricle is unable to
53.92 -> pump out blood well
55.6 -> it enlarges to accommodate the remaining
58 -> blood
59.199 -> gradually the pressure in the left
60.879 -> ventricle when it relaxes after a
63.28 -> contraction increases
65.84 -> this increase in pressure
67.76 -> is transmitted back to the left atrium
71.2 -> the upper chamber from which
73.52 -> the left ventricle receives blood when
76.56 -> it relaxes and fills
79.119 -> a rise in left atrial pressure is in
82.159 -> turn reflected onto the pulmonary veins
85.68 -> which bring oxygenated blood to the left
88.24 -> atrium from the lungs
90.56 -> increase in pressure in the pulmonary
92.32 -> veins
93.36 -> increases the pressure in the small
95.28 -> blood vessels of the lungs known as
97.52 -> capillaries
