Figure 4. Comparison of LACV with and without low-voltage areas
Left atrial conduction velocities (LACVs) were compared between patients
without low-voltage areas, with low-voltage areas limited to areas where
the propagation wave did not pass (ex-situ), and with low-voltage areas
existing across the propagation-wave route (in-situ). LACV in 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. LACV,
