Figure 1
Local activation time (LAT) map of the right atrium in a right posterolateral view during tachycardia. The focus of the tachycardia is easily seen, with earliest activation in the area that is marked in red. Black dots mark places where capture of the phrenic nerve was obvious, which is in the same region as ablation should be attempted.
Figure 2
Figure 2
Local activation time (LAT) map of the same tachycardia during the second procedure, showing the same focus of the atrial tachycardia. At the site of earliest activation a fragmented signal was noted preceding the surface p-wave with 35 ms. The green dots mark the 14 places where ablation with pulsed field energy was performed. Lesion tag size was set at 6 mm, corresponding with lesion diameters of 7.2 ± 1.6 mm seen on histologic examination with the same energy settings.
