MMC period | n | Contraction amplitude | PD deflection | Ratio |
Phase I-II | 17 | 26 (3) | −0.22 (0.04) | −8.5 (1.7) |
Late phase II | 30 | 37 (3)1-150 | −0.43 (0.06)1-150 | −13.9 (2.0) |
All | 47 | 33 (2) | −0.36 (0.04) | −11.9 (1.5) |
See Materials and Methods for definitions. Contraction amplitudes are given in mm Hg, PD deflections in mV (lumen negative polarity), and the ratios as μV/mm Hg. Values are mean (SEM).
