本文就紧急状态下,心律失常的药物治疗概述如下。 一、致命性心律失常: 致命性心律失常是指:①心室颤动。②心室停搏及重度心动过缓。 1.心室颤动:心电图:QRS波和ST-T不能辨别,基线摇摆不定。治疗:电击除颤最有效,在电除颤1～2次仍无效时,心腔内注射肾上腺素1mg,使细颤转变为粗颤,给予碳酸氢钠纠正酸中毒后,再试行电除颤。紧急时可行胸前叩击术。除颤成功后,为了预防复发,利多卡因500～1000mg加入5％葡萄糖液500ml中,以每分钟20～30滴之速度静滴,并科每隔5～10分钟给予碳酸氢钠50ml,
This article on emergency, arrhythmia drug treatment is summarized as follows. A fatal arrhythmia: fatal arrhythmia refers to: ① ventricular fibrillation. ② ventricular arrest and severe bradycardia. 1. Ventricular fibrillation: ECG: QRS wave and ST-T can not be distinguished, the baseline swinging uncertain. Treatment: the most effective defibrillation, defibrillation in 1 or 2 times is still invalid, the intracardiac injection of epinephrine 1mg, the tremor into a rough fibrillation, given sodium bicarbonate to correct acidosis, then try defibrillation . Emergency chest chest tapping surgery. After defibrillation is successful, in order to prevent relapse, lidocaine 500 ~ 1000mg added to 500ml of 5% glucose solution, infusion of 20 to 30 drops per minute, and subjects every 5 to 10 minutes to give sodium bicarbonate 50ml,
