急性心肌梗塞早期常发生心动过缓。有人认为心动过缓乃是心室颤动的一重要先兆,且为急性心肌梗塞发生院外死亡的原因之一,因而推荐阿托品作为早期的常规疗法,甚至提倡急性心肌梗塞并发心动过缓的患者,于就诊前自行肌注阿托品。本文报告一例急性膈面心肌梗塞合并心动过缓,在静脉注射阿托品后出现室性心动过速和心室颤动。病例报告:男性,63岁,于1977年6月20日因急性膈面心肌梗塞入院,症状发作后40分钟的心电图示窦性心动过缓,心律为45～55次/分。血压稳定,为90/70毫米汞柱。静脉注射阿托品0.5毫克后5分钟,心率逐渐增至130次/分,旋即出现室性心动过速,继之转为心室扑动和心室颤动,经直流电
Early onset of acute myocardial infarction often occurs bradycardia. Some people think bradycardia is an important precursor of ventricular fibrillation, and is one of the causes of hospital-acquired death in acute myocardial infarction, and therefore recommended atropine as an early conventional therapy, and even advocate acute myocardial infarction complicated with bradycardia in patients Before their own muscle injection atropine. This article reports a case of acute diaphragmatic myocardial infarction with bradycardia, intraventricular atropine occurred after ventricular tachycardia and ventricular fibrillation. Case Report: Male, 63 years old, admitted to hospital on June 20, 1977 for acute diaphragmatic myocardial infarction. The bradycardia of the electrocardiogram at 40 minutes after the onset of symptoms showed a bradycardia of 45-55 beats / min. Blood pressure was stable at 90/70 mmHg. Intravenous injection of 0.5 mg atropine 5 minutes later, the heart rate gradually increased to 130 beats / min, and then immediately appeared ventricular tachycardia, followed by the switch to ventricular flutter and ventricular fibrillation, the DC
