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.Briefly describe how ACE-inhibitors will influence Roberto’s heart function.

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.
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 the following conditions may have led to Roberto’s CHF? Faulty heart valves Hypertension Myocarditis Prior heart attacks All of these choices are correct.
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. There are multiple types of CHF. Which of these types does Roberto have? Systolic heart failure Diastolic heart failure Right-sided heart failure None of these choices is correct.
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.
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. Further testing reveals that Roberto has hypertrophy of the left ventricle. How does this finding relate to his diagnosis?
Select the FALSE statement: /////////////////www. OA) This abnormal ECG results in increased stroke volume O B) In this abnormal ECG, the ventricles are not stimulated to contract by the SA node, the natural pacemaker. of the heart O C) This abnormal ECG is compatible with life so far as the individual does not engage in strenuous activities OD) This abnormal ECG results in decreased in CO OE) None of the above
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
Although not considered the primary pacemaker of the heart, the atrioventricular node can indeed be considered as playing SOME role in setting the rhythm of the heart (kind of a secondary pacemaker). Explain how/why.
Patients with a history of heart failure often get this history from chronic hypertension. Chronic hypertension leads to a condition called hypertrophic heart disease, or hypertrophic cardiomyopathy. This means that the heart muscle gets bigger, allowing less room for it to fill with blood. If these patients take beta blockers, such as metoprolol, it will benefit them because the heart will not overwork and grow in size. However, if a patient has pulmonary edema, how could the beta blocker make this patient worse?
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. True/False 3) A person's L-type channels are mutated so that they do not inactivate. How would this affect the time duration of a cardiac action potential? 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
