美《联合会会议录》第39卷第5期(1980年)报道:区分全身麻醉剂是以其能否使心脏对儿茶酚胺所致之心律失常的作用发生敏感为基础。儿茶酚胺在麻醉期间引起的室性心律不齐似有二种不同的方式:一种方式是直接与由麻醉剂以及在儿茶酚胺注射后加压作用的反射反应引起的室上性搏动率减少有关;另一种作用(有利于室性纤维性颤动)是由心室内传导系统被麻醉剂的直接阻抑作用所引起。在目前使用的麻醉剂中,氟烷的心脏致敏作用最显著。同样的麻醉剂也可根
Vol. 39, No. 5 (1980) Proceedings of the Joint Meeting of the United States: The distinction between general anesthetics is based on their ability to sensitize the heart to catecholaminergic arrhythmias. There are two different ways in which catecholamines cause ventricular arrhythmias during anesthesia: one is directly related to a reduction in supraventricular beatiness due to the anesthetic agent and the reflexive reaction following catecholamine injection; the other The effect (favoring ventricular fibrillation) is caused by the direct repression of the intraventricular conduction system by anesthetics. Of the currently used anesthetics, halothane has the most pronounced cardiac sensitization. The same anesthetic can also root
