4.3. LACV and low-voltage area
Low-voltage
areas were more frequently observed in patients with AF recurrence than
in those without (Table 2). In addition, among patients with
low-voltages areas, the low-voltage-area size was larger in patients
with AF recurrence than in those without. Figure 4 shows a comparison of
LACVs between patients without low-voltage areas, with low-voltage areas
limited to the region where the propagation wave did not pass (ex-situ),
and
with
low-voltage areas existing across the propagation-wave route (in-situ).
LACV on the anterior route was lower in patients with in-situ (anterior)
low-voltage areas than in those without low-voltage areas. In contrast,
posterior LACV was not associated with the presence of low-voltage
areas.
