胸痛或冠心病可疑病人可有冠状动脉痉挛,在ECG监护下做麦角新碱激发试验,是一种安全的、非侵入性的诊断方法。最近,作者曾做了100例~(201)铊心肌显象检查冠状动脉痉挛,说明比ECG监护的灵敏度高,本文报道麦角新碱激发冠状动脉痉挛时同时进行~(201)铊显象、ECG监护和血管造影的比较性研究。方法:所有病人均做冠状动脉造影,检查前至少24小时停止钙阻滞剂,至少4小时停止长效硝酸盐,常规作右及左心导管,左室及冠状动脉造影,并
Suspected chest pain or coronary heart disease patients may have coronary artery spasm, under the ECG monitoring of ergometrine to stimulate the test, is a safe, non-invasive diagnostic method. Recently, the author has done 100 cases of ~ (201) thallium myocardial imaging examination of coronary artery spasm, indicating higher sensitivity than ECG monitoring reported in this article ergometrine-induced coronary spasm simultaneously 201 (201) thallium imaging, ECG Comparative study of custody and angiography. METHODS: All patients underwent coronary angiography. Calcium blockers were discontinued at least 24 hours prior to the test. Long-term nitrates were discontinued for at least 4 hours. Conventional right and left cardiac catheters, left ventricular and coronary angiography were performed and
