苄基四氢巴马汀(benzyltetrahydropal-matinc,BTHP)是从罂粟科植物延胡索(Corydalis ambigua(Pall)Cham.et Sch-lecht)中提出的异喹啉类生物碱的衍生物。实验证明BTHP有对抗多种实验性心律失常延长动作电位时程(APD)及有效不应期(ERP)、降低自律性、减慢频率等作用,
Benzotetrahydropal-matinc (BTHP) is a derivative of the isoquinoline alkaloid proposed in the Papaveraceae plant Corydalis ambigua (Pall) Cham. Et Schlecht. Experiments show that BTHP has a variety of experimental arrhythmia to prolong the action potential duration (APD) and effective refractory period (ERP), reduce self-discipline, slow down the frequency of the role,
