Adaptive Mesh Refinement and Adaptive Time Integration for Electrical Wave Propagation on the Purkinje System

Figure 4

A typical branch in the heart conduction system is highly nonuniform in the sense that the lengths of branch segments, each of which is bounded by two adjacent leaves or branching vertices, may vary significantly. In this figure, branch segments “1” and “4” are not directly connected. Instead, they are connected through a very short branch segment. Similarly, branch segments “4” and “6” are also connected through a very short segment.
