Compared with pre-ablation voltage distributions, post-ablation voltage distributions exhibit a leftward skew that is similar for both the HF and LF ablation regions. Comparing acute versus chronic time points, there is no excess increase in voltage recovery for LF compared with HF regions. Abbreviations as in Figure 2.
