呼吸衰竭常伴有心律失常。常以酸中毒、缺氧和电解质紊乱来解释,近来又着重于药物为可能因素,特别是呼吸衰竭时常用的氨茶碱。本文旨在研究氨茶碱对正常酸-碱平衡和呼吸衰竭狗的心室颤动的影响。方法:取12只狗进行实验。吸入15或 Respiratory failure often accompanied by arrhythmia. Often acidosis, hypoxia and electrolyte imbalance to explain, and recently has focused on the drug as a possible factor, especially when aminophylline commonly used in respiratory failure. This article aims to study the effects of aminophylline on ventricular fibrillation in dogs with normal acid-base balance and respiratory failure. Methods: Take 12 dogs for experiment. Inhalation 15 or
