heart disorders. What are several types of pathological conditions which alter 

 the electrocardiogram ? How is the electrocardiogram changed ? 



24. Pressure pulses are transmitted along the arterial walls for each heart- 

 beat. These travel at a much greater rate than the blood. Outline the 

 theory describing this transmission in tubes with viscoelastic walls and filled 

 with an ideal fluid. 



25. Newtonian fluids have coefficients of viscosity which are independent 

 of fluid velocity in streamline flow. Describe the experiments which show 

 that blood is non-newtonian. Characterize its viscosity.
