ture or false    The CO2 rebreathing method for measuring cardiac output can be used with strenuous exercise. During exercise, increases in heart rate will occur by inhibition of parasympathetic stimulation.

just final answer. true or false.  Training will decrease heart rate through decreasing firing rate of the SA node.

If the cardiac cycle is .86 sec what is the heart rate? Explanation

Describe how cardiac performance is measured in cardiac output. In your answer, be sure to describe the role of stroke volume (SV) and HR by defining each and discussing factors that influence SV in particular both during acute exercise and following chronic exercise training.

Check all parts of answer in boxes.  Answer last two parts with explanation. Options to choose from are charge/concentration/charge and concentration.

Question How should the blood pressure cuff be positioned on the patient? The hoses on the cuff should be facing anterior and exiting the cuff away from the hand. The hoses on the cuff should be facing posterior and exiting the cuff toward the hand. The hoses on the cuff should be facing posterior and exiting the cuff away from the hand. The hoses on the cuff should be facing anterior and exiting the cuff toward the hand Submit METHODS A RESET MY NOTES SHOW LABELS LAB DATA

Canvas ← × O During stroke volume, the pressure in the ventricles forces AV and semi-lunar valves open D O True O False Question 41 X The sound is heard during ventricular systole O True O False Question 42 To calculate EDV, you must sum SV and ESV O True O False

Please I need help understanding this question, I'm not sure if I'm understanding it right.

just final answer    Volume of blood flow in a blood vessel relates to two factors:   Select 2 correct answer(s)   Directly to pressure gradient between two ends of the vessels   Inversely to pressure gradient between two ends of the vessels   Directly to resistance encountered to fluid flow   Inversely to resistance encountered to fluid flow

The Importance of the Electrocardiogram and Holter Monitor in the Cardiovascular System Instructions The standard EKG consists of 10 sensors that record 12 leads of the heart’s electrical activity from different angles, allowing for a thorough three-dimensional interpretation of its activity. This is transmitted by the electrodes to the equipment to be interpreted and is used to diagnose cardiac medical conditions. In case of an abnormal EKG, the second step would be to use a Holter monitor. Questions Where will you place the electrodes when performing and EKG? Why? What are the different lead types, connections, and placements? When you conclude an EKG, what are the different components that you need to observe and confirm before you disconnect the patient? Can you explain the difference between normal, abnormal, and artifacts? What is a Holter monitor? Under what circumstances would one be ordered for a patient? How do you use a Holter monitor? Educate a patient: What you…
