Step by step
Solved in 2 steps
- What’s the meaning of cardiologyWhich of the following situations might indicate the need for an artificial pacemaker? Group of answer choices The AV node is not sending signals to the ventricles. The SA node is not functioning properly to generate action potential at the proper intervals. The Purkinje fibers are not distributing the signal properly. The heart valves are not directing blood flow through the chambers properly.Chordae tendineae: Group of answer choices hold the AV valves in place. contract when the heart contracts. are one part of the conductance system of the heart. regulate blood flow into the ventricles. are stretched during ventricular systole.
- why cardiac therapy is for the worst?Why is it important for medical coding and billing specialists to know about the cardiovascular system in their roles?You are working in cardiopulmonary rehabilitation. It is your patient, Dave’s, first day of rehab. Dave had a heart attack 45 days ago. He is 40 years old and feels comfortable and confident enough to walk on a treadmill or ride a bike. Upon talking with Dave, you learn that he regularly exercised up until his heart attack. He completed resistance training 3 days/week at his local gym and would play tennis with friends several days each week. He can walk comfortably without an assistive device on flat surfaces at his own speed. You need to determine Dave’s VO2 in order to create a correct exercise prescription. Would you test this person, yes or no? If yes, please indicate what protocol you would choose and whether or not the test would be maximal or submaximal? Please include your rationale.
- The Effects of Lifestyle, Sex & Genetics on Blood Pressure Many things might affect heart rate, including the physical fitness of the individual, the presence of drugs such as caffeine or nicotine in the blood, and the age of the person. Heart rate and blood pressure work together to ensure that blood reaches cells at a rate that is sufficient to supply nutrients and remove waste products. If one variable decreases the other will increase to maintain this balance. For example, if the body detects a drop in blood pressure, it will help to correct this imbalance by increasing heart rate until the body can adjust blood pressure by other methods. Watch these videos to learn the terminology and science of blood pressure along with how to take a proper blood pressure reading. https://www.ausmed.com/cpd/articles/how-to-take-blood-pressure When a person is well hydrated and healthy the body can make these adjustments without you ever being aware. But, if a person is dehydrated, taking…What keeps the atrioventricular (AV) valves from being pushed open as the ventricles contract? Pressure of blood pushing against the valves. Contraction of the atria. Closure of the semilunar valves. Contraction of papillary muscles and tightening of chordae tendineae.Blood pressure depends on: Group of answer choices the height and weight of an individual. atrial volume and stroke rate. blood flow and resistance of blood against the vessel walls. total blood volume. heart rate.
- The semilunar valves prevent blood from moving: Group of answer choices from the atria back into the veins. from the ventricles back into the atria. from the arteries back into the ventricles. moving backward in the capillaries. moving backward in the arteries.Which organs or tissues get a lot of blood flow as exercise is happening? Skeletal muscles Skin Digestive system Brain Kidneys HeartA student nurse is measuring a patient’s pulse rate and the patient places his free hand against his neck.
