Fig. 5From: Epicardial infrared ablation to create a linear conduction block on a beating right atriumAtrial potentials pre-ablation and post- ablation (S: stimulation). Biphasic atrial potentials were recorded (A1 and A2). Both S-A1 conduction time and S-A2 conduction time were prolonged after the 28 s of ablation, and the conduction prolongation ratios were 1.43 and 1.38, respectivelyBack to article page
