Methods: The study was conducted as the defibrillation study, and ventricular fibrillation (VF) induction study. In both studies, the defibrillation threshold (DFT), the upper limit of vulnerability (ULV) and VF threshold were determined before and after KP extract administration.
Results: In both studies KP extract at high concentrations (100 and 50 mg/kg) significantly increased the DFT and ULV, without altering the VF threshold. At these concentrations, systolic and diastolic blood pressures were also attenuated.
