Question

The following medications are used to treat an exacerbation of congestive heart failure. Each one of them is actually used to counteract mechanisms the body has naturally set in place in response to a drop in blood pressure and presumed drop in tissue perfusion. For each medication, explain its affect(s) on A, B, and C. If you feel it has no effect on a particular parameter, then say "no effect".

Specifically for each:

A) affect on TPR (total peripheral resistance) and how/why it changes it
B) affect on cardiac output (contractility, heart rate, stroke volume) and how/why it changes it
C) blood volume/pressure and how/why it changes it
ACEIs (ACE inhibitors)
Beta blockers
Digoxin
Nitrates (nitroglycerin, isosorbide)
Diuretics like Lasix

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.
1)An increase in total peripheral resistance, all else remaining the same, will cause an increase in mean arterial pressure.True/False 2) We care about mean arterial pressure specifically because we care about having an appropriate rate of blood flow through capillaries.

Group of answer choices a)Increase b)No change c)Decrease 4) A person' L-type channels are mutated so that they do not inactivate. How would this affect the time duration of a cardiac muscle cell contraction? Group of answer choices a)Increase b)No change c)Decrease
Roberto is a 78-year-old male who has recently been diagnosed with Class III Congestive Heart Failure (CHF). His physician told him that his left ventricle has become stiff and cannot relax. Although there is no current treatment that can “fix” Roberto’s condition, he is prescribed two medications: an ACE inhibitor and beta blockers. Which of these statements is most likely true of Roberto’s current symptoms? He doesn’t experience any symptoms at all at rest or during exercise. He has no symptoms at all during rest, but experiences palpitations, fatigues, and shortness of breath during mild exercise. He experiences fatigue, shortness of breath, and palpitations at rest and is not able to participate in any physical activity.
a) A consequence of the Frank-Starling law of the heart is that the outputs of the right and left ventricles match.

How might these differences be related to the difference between action potentials in cardiac muscle and skeletal muscle?
