本文报告一例急性心肌梗塞(AMI)在超急性及急性期因窦性心动过速(窦速)和 QRS波群电压变低诱发室颤(VF)四次。本例经及时抢救治愈。介绍如下:患者王××,男、60岁,退休工人。因心前区疼痛半小时,于1984年7月4日凌晨3时来我院急诊。患者有劳力性心前区疼痛两年史,半个月来发作频繁,1—2次/日,5—10分/次,含硝酸甘油可缓解。本次发作持续半小时,有濒死感,伴大汗,含硝酸甘油无效。就诊时查 BP 150/90mmHg,HR80次分,律齐,双肺清,EKG 示:实性心律(80次/分)S—TⅡ、Ⅲ,avF 呈水平型下降0.05mV,S—Tv_3v_5抬高0.2—0.3mv,Tv_3高耸达1.2mv(见图一)。初诊为梗塞前心绞痛。经先后肌注杜冷丁(50mg)、罂粟硷(30mg)和静点
This article reports a case of acute myocardial infarction (AMI) inducing ventricular fibrillation (VF) four times in hyperacute and acute phases due to sinus tachycardia (sinus speed) and QRS complex voltage depression. In this case, timely rescue and cure. Described as follows: Patient Wang × ×, male, 60 years old, retired workers. Because of precordial pain for half an hour, at 4:00 on July 4, 1984 to our hospital emergency room.

The attack lasted half an hour, with sense of nearness, with sweating, nitroglycerin ineffective. At the time of treatment, BP 150 / 90mmHg, HR80, Laws, double lung clear, EKG showed: S-TⅡ, Ⅲ, avF decreased by 0.05mV and S-Tv_3v_5 increased 0.2-0.3mv, Tv_3 towering 1.2mv (see Figure 1). Newly diagnosed as pre-infarction angina. After intramuscular injection of pethidine (50mg), papaverine (30mg) and static point
