Effect of Berberine on Reperfusion Arrhythmias in the Isolated Rat Heart / 第二军医大学学报

Effect of-berberine on reperfusion arrhythmias was studied using a 10 rain left anterior descending coronary artery occlusion followed by reperfusion in the isolated rat heart. Berberine, when given 10min before coronary ligation, reduced the incidence of reperfusion arrhythmias in a dose-riependent manner. With 10-5, 3. 16?10-5 and 10-4 mol/L of berberine, ventricular fibrillation was reduced from its control incidence of 100% to 90%, 70% and 40% (P
