anisotropic computer heart models were conducted to
study the effects of myocardial anisotropy on the
excitation process of the heart and on body surface
electrocardiogram. The isotropic heart model includes
atria, ventricles, and a special conduction system, and
is electrophysiologically specified by parameters
relative to action potential, conduction velocity,
automaticity, and pacing. The anisotropic heart model
was created by incorporating rotating fiber directions
into the ventricles of the isotropic heart model. The
orientation of the myocardial fibers in the ventricles
of the model was gradually rotated counterclockwise
from the epicardial layer to the endocardial layer for
a total rotation of 90 degrees. The anisotropy of
conduction velocity and intracellular electric
conductivity was included in the simulation.
Comparative simulations of the normal heart, LBBB, and
RBBB showed no significant differences between the two
models in the excitation processes of the whole heart
or in the body surface electrocardiograms. However, it
was easier to induce ventricular fibrillation in the
anisotropic model than in the isotropic model. The
comparative simulation is useful for investigating the
effects of myocardial anisotropy at the whole heart
level and for evaluating limitations of the isotropic
heart model.",
