槐胺碱(20mg/kg)静脉注射可拮抗乌头碱(20μg/kg)、BaCl_2(4mg/kg)在大鼠所诱发的心律失常(P<0.05),拮抗氯仿-肾上腺素所致的兔心律失常。在豚鼠槐胺碱增加哇巴因诱发室早,室速、室颤及心跳停止所需要的用量。此药在10～20mg/kg腹腔注射还可减少氯仿所致的大鼠室颤,和乙酰胆碱-CaCl_2研致的房颤(扑),槐胺碱显著降低大鼠的心率并拮抗异丙肾上腺素的正性变速作用。 Intravenous injection of anthracycline (20 mg/kg) antagonized the arrhythmia induced by aconitine (20 μg/kg) and BaCl 2 (4 mg/kg) in rats (P<0.05), and antagonized rabbits induced by chloroform-adrenaline Arrhythmia. In guinea pig amphibious base increased ouabain induced premature, ventricular tachycardia, ventricular fibrillation and cardiac arrest required for the amount. Intraperitoneal injection of this drug in 10 ~ 20mg/kg can also reduce chloroform-induced rat ventricular fibrillation, and acetylcholine-CaCl2 developed atrial fibrillation (pan), amidine significantly reduced rat heart rate and antagonize isoproterenol Positive shift effect.
