Why is the Frank-Starling law of the heart important to the understanding of heart failure?
Step by step
Solved in 3 steps
- What is the Frank-Starling law of the heart? What is its significance?What is the Frank–Starling law of the heart? What is its significance?a) A consequence of the Frank-Starling law of the heart is that the outputs of the right and left ventricles match. Explain why this is important and how this match is made.b) The excitation-contraction matching mechanism within the heart muscle is different from that of the skeletal muscle. How might these differences be related to the difference between action potentials in cardiac muscle and skeletal muscle?
- Why do we need to prevent the decompensated state in patients with heart failure?Explain the principle behind the Frank–Starling law of the heart. How does this mechanism normally prevent pulmonary or systemic congestion?Describe the action potential of an autorhythmic cell in the heart.a) Indicate how the opening and closing of each ion channel affects the membrane potential of the cell.b) Provide one similarity between the action potential of an autorhythmic cell and the action potential of a neuron.c) Provide one difference between the action potential of an autorhythmic cell and the action potential of a neuron.
- How can an individual’s maximum heart rate be estimated explain with a formula?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.Briefly define 1) Starling’s Law of the heart, 2) the basic cellular mechanism thought to mediate this response, and 3) the physiological significance of this effect.
- 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 LasixFrank-Starling law of the heart states: if you increase the stretch of the cardiac muscle fibers you will decrease the force of contraction a greater end diastolic volume will produce a weaker contraction of the ventricle by increasing the force of ventricular contraction you will increase the end systolic volume if you increase the stretch of the cardiac muscle fibers you will increase the force of contraction.In a patient given a cardiac glycoside, important effects of the drug on the heart include which of the following? a) Increased force of contraction. b)Decreased atrioventricular conduction velocity c)Decreased ejection time d)Increased ectopic automaticityAll of the above
