作者对疑有血管痉挛性心绞痛患者,给予马来酸麦角(ergonovine maleate,EM)负荷,诱发冠脉痉挛,对急性心肌缺血时室性心律失常,尤其是室早波形变化及向室速转变问题加以研究。对象:对疑有血管痉挛性心绞痛患者给予EM 负荷,出现5个以上室早者共18例。平均年龄51.0±10.4(29～65岁),男15例,女3例。方法:EM 用量根据各例自觉症状,最近发病情况及对比造影所见来决定。0.05～0.2mg 注入主动脉基底部Valsalva 窦内。如不出现心绞痛及EKG 变化,最大量可用到0.4mg。出现心绞痛等自觉症状或ST 段上升时,立即进行冠脉造影,观察有无冠脉病变及痉挛发生部位。
In patients with suspected angina spastic angina, ergonovine maleate (EM) load was given to induce coronary spasm, and ventricular arrhythmias in acute myocardial ischemia, especially changes in ventricular premature ventricular and ventricular tachycardia Problems to be studied. Subjects: Patients with suspected angina spastic angina were given EM load, with more than 5 cases of early 18 cases. The average age was 51.0 ± 10.4 (29 ~ 65 years), 15 males and 3 females. Methods: The dosage of EM was determined according to the symptoms of each case, the recent incidence and contrast imaging. 0.05 ~ 0.2mg into the aortic base Valsalva sinus. In the absence of angina pectoris and EKG changes, the maximum amount available to 0.4mg. Angina pectoris and other symptoms or ST-segment rise, the immediate coronary angiography, coronary artery disease were observed and spasticity occurred.
