“2) In partially depolarized papillary muscles, resveratrol (60 micromol/L ) not only shortened APD , but also decreased the amplitude of action potential (APA), overshoot (OS) and maximal rate of depolarization in phase 0 (Vmax). (”
“The results obtained are as follows: (1) In normal papillary muscles, resveratrol (30, 60, and 120 micromol/L) shortened the duration of action potential ( APD ) in a concentration-dependent manner. (”
