Simulation of Ectopic Pacemakers in the Heart: Multiple Ectopic Beats Generated by Reentry inside Fibrotic Regions

Table 2

Left-right, . Each cell (discrete model) or discretized volume (microscopic model) was classified as NA (no activity), A (a single AP, no reentry), S (sustained reentry, multiple APs until the end of the simulation), or NS (nonsustained reentry, multiple APs, but activity stops, dies out, before the end of the simulation). The table presents the percentage of area of the tissue for each category. In addition, for the category NS we present the time the reentry dies out or stops.

Type	Run 1		Run 2
	Microscopic	Discrete	Microscopic	Discrete
NA	54.1%	51.7%	55%	53.5%
OA	18.3%	16.2%	15.6%	14.4%
S	19.2%	32.1%	17.3%	20.9%
NS	8.4% (stops at 216 ms)	0%	12.1% (stops at 223 ms)	11.2% (stops at 217 ms)
