治疗予激综合征合并窒上性心动过速、心房纤颤、心房扑动时,因房室之间存在正常房窒传导系统和与解剖和电生理特性相异的旁道,故有几点与一般情况不同的事项必须注意。第一,二条传导通路对药物的反应不同。例如,若室上性心动过速是由于包含旁道通路的循环激动所引起,则用抑制旁道传导的药物如普鲁卡因酰胺,可中止其发作。若室上性心动过速与旁道无关,仅局限于房室结,则普鲁卡因酰胺不能中止室上性心动过速,而洋地黄可以奏效。但也有完全相反的情况,故确定
Treatment of irritability syndrome with suffocation tachycardia, atrial fibrillation, atrial flutter, due to atrioventricular tachycardia between the normal conduction system and anatomical and electrophysiological characteristics of the bypass, so what is the point Things that are different from the normal situation must be noted. The first and second conduction pathways respond differently to the drug. For example, if supraventricular tachyarrhythmias are caused by a cyclic activation of the bypass pathway, the onset of the episode can be stopped with drugs that inhibit side-channel conduction, such as procainamide. If supraventricular tachycardia has nothing to do with the bypass, is confined to atrioventricular node, procainamide can not stop supraventricular tachycardia, and digitalis can work. But there are also the opposite situation, so OK
