Figure 5. One-dimensional sinoatrial node fiber model.

Figure 5

(A) 50 mouse SAN cells are electrically coupled to 50 mouse atrial cells to create a one-dimensional fiber. (B) Spontaneous action potentials along the fiber during five consecutive cycles at steady-state. (C) Activation time and (D) dV/dtmax along the fiber during one cycle at steady-state.
