作者以奎尼丁—异搏定(Chinidin—Verapamil)对30例心房纤颤,心房扑动,室上性及室性期前收缩患者进行了长期门诊治疗。奎尼丁为一种钠拮抗剂,阻止细胞去极化时钠盐流入,钾盐外流,从而延缓了自动节律性和反拗期,奎尼丁尚具有抗胆碱作用从而能加速房室间传导。异搏定为一种钙拮抗剂,能抑制慢反应动作位相,该作用在生理情况下出现于房室结,病理情况下则出现于受损的卜倾野氏纤维。因此,这些组织的激动传导被
The authors conducted a long-term outpatient treatment of 30 patients with atrial fibrillation, atrial flutter, supraventricular and ventricular premature contractions using Chinidin-Verapamil. Quinidine as a sodium antagonist to prevent cell depolarization sodium influx, potassium outflow, which slowed the automatic rhythm and anti-stubborn, Quinidine has anticholinergic effect to speed up the inter-atrioventricular Conduction. Verapamil as a calcium antagonist, can inhibit the slow reaction phase, the role in the physiological situation in the atrioventricular node, pathological conditions appear in the damaged Buye wild fiber. Therefore, the excited conduction of these organizations is
