Abstract

In Langendorff preparations of rat heart, hyperkinetic ventricular arrhythmias (HVA) have been induced by an ischaemic perfusion (coronary flux 0.5 ml/min; pressure 8 mmHg) and following reperfusion at basal conditions (coronary flux 8 ml/min; pressure 50 mmHg). Crude methanolic extracts of Harpagophytum procumbens secondary roots and harpagoside showed a significant, dose-dependent, protective action toward HVA induced by reperfusion.
