    2.3. Pulsatile Flow Pulsatile flow is such a flow that varies with time. Another property of pulsatile flow is that it is usually periodic in nature that is‚ a specific flow pattern is repeated over time. This type of flow can be found in the cardiovascular system of chordate animals‚ where the heart produces the pulsatile flow [9]. The phenomenon of de-polarization and re-polarization of atria and ventricles is an example to produce pulsatile flow in human hearts. An electrocardiogram (ECG) plot
