Summary Introduction
To review:
The symptoms and signs produced as a result of mitral insufficiency, the effect of this disease on CO (cardiac output) and theSV (stroke volume) of the patient, and the treatment that could help the patient to improve their CO.
Introduction:
The mitral valve is present on the left side of the heart. It prevents the backward flow of blood after atrial contraction. During mitral insufficiency, the mitral valve fails to close properly. In this condition, the blood flows backward, that is, from the heart’s ventricle to the atrium. The backward flow of blood is referred as regurgitation.

I need to calculate the approximate heart rate based on the given ECG results, but I can't get how to determine the length of time between two consecutive R waves. What I see, it's one second between the two highest waves (I suppose they are R waves). But it means the heart rate should be 60 beats per minute, but there is no option for this answer. Teach me how to determine correctly the length of time between two consecutive R waves.
Indicate the correct order of the sequence of events occurring during congestive heart failure. Order the sentences (Hint: End with "g")
This question is a great summary of what happens, in steps, in congestive heart failure.
a. narrowed bicuspid valve makes the L atrium pump harder in order to "push" blood into the L ventricle through an opening that is too narrow.
b. pressure of the extra, backed up blood in the lung creates pressure in the capillaries that begin to leak fluid into the lung.
c. extra "left-over" blood in the atrium that has not descended into the ventricle after a beat has nowhere to go.
d. congenital heart defect causes a narrowed bicuspid valve
e. not all blood gets "pushed" from the L atrium to the L ventricle during a regular heart beat
f. blood that backed up in the L atrium with nowhere to go backs up further, into the pulmonary veins and eventually into the lung
g. the patient gets less oxygen with each breath, feels tired all the time and is…
