In this elecrical analogue the left atrial activity is implemented using the numerical model described in the "Atrial Numerical Modelling [1]" section.  The ascending aorta and the aortic arch are modelled with RLC elements, left brain, right brain and arms are modelled with resistances and compliances. Systemic venous circulation is divided in two compartments implemented with RC elements. LAP (LVP) is the left atrial (ventricular) pressure, AoP is the aortic pressure. Mitral and aortic valves are modelled with resistances and diodes.

Aortic arch (II) and intercostal circulation compatment is implemented with two resistances (R_CHEST1 and R_ARCA2), an inertance (L_ARCA2) and a compliance (C_ARCA2). Three comparments are used to reproduce the behavior of thoracic and intercostal circulation, each compartment is modelled with two resistances (R_CHEST and R_THOR), one inertance (L_THOR) and one compliance (C_THOR). Hepatic circulation is implemented with resistance (R_LIV) and compliance (C_LIV).

The abdominal circulation is divided in two branches both modelled with RLC elements. Two kidney compartments reproduces the left and right kidney circulation; both comparments are implemented with RC elements: R_LKUI and C_LKUY for left circulation and R_RK and C_RK for right circulation. The behavior of legs and lower mesenteric circulation is simulated with two resistances (R_CDI and R_PDI) and one compliance (C_DI).
