Figure 3.
Computational model result showing snapshots of transmembrane potential across simulated myocardial tissue. For these models a 5 mm by 5 mm plane of tissue was simulated. Each row represents a different model and the panels in a row show snapshots as time progresses going from left to right. With no ablation line (top row) the depolarization spreads to cover the entire tissue. With an ablation line and a 1.5 mm gap of normal conductivity the depolarization propagates through the gap to cover the entire area. With an ablation line and a 1.3 mm gap of normal conductivity the depolarization does not propagate through the gap area resulting in conduction block.
