Effects of Acetyhlcholine and Berberine on Atrial Action Potential Duration (ms)

APD50 APD90
Baseline 152 ± 13 256 ± 19
ACh 81 ± 11* 132 ± 13*
Ach+Ber 134 ± 15# 213 ± 17#

P<0.05 vs. ACh+Ber.

Units of APD are msec. ACh: acetylcholine, Ber: berberine, APD50: duration of the action potential to 50% of repolarization; APD90: duration of the action potential to 90% of repolarization.
