A Pilot Study on Parameter Setting of VisiTag™ Module during Pulmonary Vein Isolation

Figure 1

An example of different parameter settings of the VisiTag™ module for pulmonary vein isolation: a 3 mm maximal moving range of the catheter and 20 s minimal stability time of the ablation catheter were constant. (a) FOT setting being zero; (b) FOT setting being minimal force 5 g with 50% stability time; (c) FOT setting being minimal force 10 g with 50% stability time. Different color lines indicated different segments of ablation line. White arrow indicated a TG at the situation of FOT setting being a minimal force of 5 g with 50% stability time, which did not display when FOT setting is zero. FOT: force over time; LEAL: left encircling ablation line; REAL: right encircling ablation line.
