盐酸利多卡因可有效地治疗与急性心肌梗塞、洋地黄中毒、心脏手术及心脏插管有关的室性心律失常。因其发生作用快而对血液循环的抑制较小,所以治疗剂量的利多卡因被广泛地应用于治疗心肌梗塞中的室性期外收缩。虽然偶也可产生心血管系统的副作用,但由治疗剂量所致的窦房结抑制尚未见有报道。本文报告1例88岁女性急性前壁及心内膜下心肌梗塞患者,为治疗频发的室性期外收缩,在应用治疗剂量的利多卡因静注后发生了致死性的窦性停
Lidocaine hydrochloride is effective in the treatment of ventricular arrhythmias associated with acute myocardial infarction, digitalis poisoning, cardiac surgery, and cardiac catheterization. Lidocaine at a therapeutic dose is widely used to treat ventricular extrasystoles in myocardial infarction because of its rapid onset of action and less inhibition of blood circulation. Although even can produce cardiovascular system side effects, but the therapeutic dose of sinoatrial node suppression has not been reported. This article reports an 88-year-old woman with acute anterior wall and subendocardial myocardial infarction patients, for the treatment of frequent ventricular contraction, the application of therapeutic doses of lidocaine after intravenous fatal sinus stop
