Impact of Decreased Transmural Conduction Velocity on the Function of the Human Left Ventricle: A Simulation Study

Figure 1

Electrical equivalent scheme of the model of left heart and systemic circulation. The individual symbols in the scheme stand for the left atrium and ventricle (LA, LV); atrioventricular and aortic valves (, ); inertia of blood (); resistance against the blood flow in aorta, in peripheral vessels, and in the terminal part of the venous system (, , ); viscoelastic compliance of the initial segment of aortic arch (, ) and of the remaining aorta (, ); and elastic compliance of the terminal part of the venous system (). The symbols , , , , and stand for the pressures in the left atrium, left ventricle, aortic arch, aorta, and venous system. Q_a represents blood flow in aorta. The values of individual parameters are specified in Table 1.
