Chronotropic Modulation of the Source-Sink Relationship of Sinoatrial-Atrial Impulse Conduction and Its Significance to Initiation of AF: A One-Dimensional Model Study

Figure 4

CL changes related to source-sink properties. Same representations of Figure 3 are reported for control (NT) conditions (a), 74% downregulation (b), and 61.5% downregulation (c), with the -axis representing a color contour map for corresponding CL values. Average CL values in P&D conditions are indicated with colored arrows pointing to the color bar on the right.
