Image-Based Structural Modeling of the Cardiac Purkinje Network

Table 1

Summary of differences in activation times between the 3D-3D and 3D-2D rabbit and canine models according to three different schemes: measured with respect to the start of the stimulation protocols, first ventricular activation, or to minimize the root mean square difference. Measurements are given in milliseconds. For signed quantities, the 3D-2D activations times were subtracted from the 3D-3D activations times.

Rabbit models	Stimulus start	First ventricular activation	Minimizing RMS
Root mean square difference	4.4	0.9	0.7
Standard deviation of differences	0.7	0.7	0.7
Minimum difference	−7.2	−3.3	−2.7
Maximum difference	−2.0	+1.9	+2.4
Canine models	Stimulus start	First ventricular activation	Minimizing RMS
Root mean square difference	1.4	1.4	1.4
Standard deviation of differences	1.4	1.4	1.4
Minimum difference	−6.8	−6.8	−6.5
Maximum difference	+2.8	+2.8	+3.1
