BME5401/BME4409 Homework 3. Due date Oct 12, 2011 1. Use the simulation file from homework 1. Remove the sinewave generator, and the output port. Then highlight all components and select Edit->Create subsystem. Paste a screen shot of the result below. Note: if you have not saved the simulation, you start with a copy from a fellow student 2. Create an approximation of the left ventricle cardiac activation function by using a piecewise linear approximation as in the following graph. Hint: look at the “Repeating sequence interpolated” object. Connect the output to a Scope. You may have to set the solver to fixed-step in Simulation->configuration. Emax=4, Emin=0.09, Tvs=0.3, heart rate (HR)=70. Simulate for 10 seconds, cut and paste the result from the scope. 3. Increase the heart rate to 120. Run the simulation, cut and paste from the scope. 4. The pressure generated by the left ventricle can be defined as Plv(t) = e(t)*(v(t)-UV), where e(t) is the activation function (see 2.), v(t) is the
