Table 2. Comparison of Absolute Decrease in Conduction Velocities by 10 μm Local Anesthetics at PCL 1,000 and 600 ms

*P < 0.01 versus  the corresponding variable in the racemic (Rac) bupivacaine group. Racemic bupivacaine tended to decrease θT more than the other agents at pacing cycle length (PCL) 600 ms (P = 0.06).

ΔθL and ΔθT = absolute decreases in longitudinal and transverse conduction velocities, respectively.
