Page 1 Part 1: Estimate the period of each function, and determine the midline, amplitude and frequency. Show all work/thinking. 1. Determine if the aortic pressure function, P(t), appears to be periodic in nature. Explain why or why not. a 20 b) input output 0 2 10 14 Distance above the water (feet) 2 VOUAWN- 10 2. Describe what the graph above tells us about the aortic pressure in the heart over two periods. Be specific. 14 2 L-15 10 Time (seconds) Period Period Midline 3. Estimate the average rate of change from t = 0.8 to t = 1.6 seconds. What does this rate of change Midline. tell us about the aortic pressure during this interval of time? Amplitude. Amplitude Frequency Frequency Part II: The diagram below is a graphical representation of various forces that typically occur in the ventricle of the heart. (Source: http://en.wikipedia.org/wiki/Cardiac_cycle ) 4. Estimate the amplitude of the graph of P(t) and explain what this means in this context. Isovolumic relaxation Itor olun Rapid inflow Diastasis | Atrial systole Aortic Aortic table opens doses Aortic pressure doses 5. Based upon the graph P(t), give the practical domain of the function and explain why you selected trial pressure the values you did. Volume (ml) Pressure (mmHg) "Ventricular pressure Ventricular volume Electrocardiogram Ist Phonocardiogram 6. Based upon the graph P(t), give the practical range of the function and explain why you selected the Systole values you did. Diastole Systole Time, in seconds 0.8 1.6
