作者通过对一组变异型心绞痛患者进行过度换气和麦角新碱试验,来评定两种试验的敏感性,并用心绞痛自行发作的次数加以矫正。方法:30例患者均在休息时出现胸痛,舌下含服硝酸甘油后迅速缓解,同时,心电图上至少有二个导联 ST 段抬高≥1mm,症状缓解后,ST 段仍回复至基线。所有病人除必 The authors assessed hyperinflation and ergonovine in a group of patients with variant angina to assess the sensitivity of both tests and corrected the number of spontaneous episodes of angina pectoris. Methods: Thirty patients had chest pain at rest and sublingual nitroglycerin, which was relieved quickly. At the same time, ST segment elevation was ≥1 mm in at least two leads on ECG. After symptom relief, ST segment still returned to baseline. In addition to all patients must
