Table 3. Effects of MMA on Normal and Slow Action Potential Characteristics at 0.25 Hz Stimulation Rate
Values are mean ± SD.
* Differences from baseline (P < 0.05).
† Differences from 1.5 mm MMA (P < 0.05).
AP = action potential; APD50, APD90, and APD30= duration of AP at 50, 90, and 30% repolarization, respectively; dV/dt-max = the maximum rate of depolarization of the AP; MMA = methymethacrylate monomer.
