Textbook Question
Chapter 42, Problem 13PIAT
QUANTITATIVE Researchers used echocardiography, a sonogram of the heart, to estimate the mass of the left ventricle in current athletes, non-athletes, and ex-athletes. The data are graphed below (*** means P<0.001, and the P value comparing non-athletes and ex-athletes is > 0.05; see BioSkills 3 ). What conclusion can be drawn from the graph?

- Estimate the volume of a human heart (in mL) using the following measurements/assumptions: Blood flow through the aorta is approximately 16.8 cm/s. The diameter of the aorta is approximately 3.0 cm. Assume the heart pumps its own volume with each beat. Assume a pulse rate of 90 beats per minute.arrow_forwardI 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.arrow_forwardBrink studied the effect of postural change on cardiovascular reactivity for a sample of healthy white and African American men and women. Change in systolic blood pressure (SBP) from supine to standing position was used as the measure of cardiac reactivity in a sample of 842 adults. Supine measurement of blood pressure was taken after participants had lain on an examination table for 15 minutes. Blood pressure was measured five times every 2 minutes using a preset automated blood pressure monitor, and the five measurements were averaged. Participants then stood up, and an additional five measurements were made over another 10-minute period and then averaged. Below is a table describing the characteristics of Brink’s sample.

- Throughout the development of prosthetic heart valves, how might application of nanotechnology be used to improve the strength of the prosthetic heart valves and reduce complications and failures? Discuss.arrow_forwardBased on the results shown in Figures 2A and 2B, was there a significant change in TP interval in either group? Explain your results using your knowledge of the cardiac cycle and of how the heart is regulated by electrical activity.arrow_forwardAn artificial heart works in closed loop by varying its pumping rate according to changes in signals from the recipient's nervous system. For feedback compensation design it is important to know the heart's open-loop transfer function. To identify this transfer function, an artificial heart is implanted in a calf while the main parts of the original heart are left in place. Then the atrial pumping rate in the original heart is measured while step input changes are effected on the artificial heart. It has been found that. in general, the obtained response closely resembles that of a second-order system. In one such experiment it was found that the step response has a %OS = 30% and a time of first peak 7, 127 sec (Nakamura, 2002). Find the corresponding transfer function. Aside from the corresponding transfer function, determine the following as well: delay time, rise time, settling time and steady state error if input is a step response. CO Marrow_forward
