In Silico Evaluation of the Potential Antiarrhythmic Effect of Epigallocatechin-3-Gallate on Cardiac Channelopathies
Effects of 30 μM E3G on atrial cell action potentials for -WT and -p.R222Q conditions (MGTG cell model). (a), (b), and (c) Simulated APs (Top of the panels) and the cardiac sodium currents (Bottom of the panels) in WT, heterozygous -p.R222Q, and heterozygous -p.R222Q + 30 μM conditions at 1 Hz cycle length. Arrows: external stimulus. (d) and (e) Strength-duration curves in the MGTG cell model for -WT and heterozygous -p.R222Q conditions with or without 30 μM E3G (inset, zoom on the strength-duration curves). (f) Excitation thresholds at 2 ms stimulus duration in the MGTG atrial AP or without 30 μM E3G.
