3.2 Study characteristics
The characteristics of the included trials and ablation settings are
shown in Table 1. A significant difference in power delivery setting was
found between the HPSD and LPLD groups. There is no consensus about the
power and duration settings for HPSD, in our study, energy levels above
40 W are considered as high power and duration of application for
2~10s as short
duration4,
13, 14,
17-20. All patients received PVI,
additional linear ablations were performed in select patients at the
operator’s discretion in some
trials4,
18, 19 . All studies
had good methodological quality. The results of the grouping ensured the
feasibility of this meta-analysis.
