  1. SHAM: sham-operated, OVX: ovariectomized, E2: 17β-estradiol, EXD: Er-Xian decoction, RMP: resting membrane potential, Vmax: maximal rate of depolarization, APA: AP amplitude, APD50: AP duration at 50%, APD90: AP duration at 90%. Values are presented as the means ± SD (n = 9 in each group). * P < 0.05 versus SHAM group; ** P < 0.01 versus SHAM group; # P < 0.05 versus OVX group
