Model introduction
The model can be used either with all four chambers or as a biventricular model.
Fig. 28 The setup uses a regular tetrahedral FE model, representing a 3-D slab of myocardial tissue with dimensions 1.50cm x 0.01cm x 1.00 cm (l,w,h) in the x-, y, and z-directions stimulated at the left front side. A conductive bath is attached along the +y and -y faces of the wedge, thus forming a tissue bath interface along which bath loading effects will occur.
2-Chamber configuration
The 2-Chamber configuration is selected using the input parameter --geometry 2C.
Sinus activation
Wavefront propagation is initiated at the His bundle by the input parameter --purkStim His.
We use a normal His-Purkinje system (HPS) which is selected through --purkinje normal.
As we are only interested in the sinus activation we turn of any stimulation
which would trigger additional activations. This is achieved by setting --stimulus none.
./run_ep_v2.py --geometry 2C --purkStim His --purkinje normal --duration 50 \
--propagation R-E- --stimulus none --ID 2C_His_sinus_activation --visualize
Note
The 4C model in its current incarnation is only a baseline model for technical testing. Any capabilities in terms of more useful stimulation protocols must be added.
