该研究旨在评价硷中毒激发试验对于偶发静息胸痛病人的安全性及诊断价值。方法:对237例静息心绞痛进行分型,记录胸痛时间、部位及放射范围,常规进行临床、生化及X线检查。仅亚极量运动试验阴性病人进行过度通气激发试验。运动中达到预计最大心率(220-年龄)的90％而无胸痛、无缺血性ST段变化作为阴性。下列病人剔除:既往有心肌缺血(胸痛时心电图改变)、气道阻塞病、65岁以上。试验均在上午9～11时进
The aim of this study was to evaluate the safety and diagnostic value of alkalosis challenge test in patients with recurrent chest pain. Methods: 237 cases of rest angina pectoris were typed, time of chest pain, location and radiation range were recorded, and routine clinical, biochemical and X-ray examination. Only submaximal exercise test negative patients with hyperventilation test. 90% of the expected maximum heart rate (220-years) was achieved without chest pain and no ischemic ST-segment change was negative. The following patients were excluded: past myocardial ischemia (chest pain ECG changes), airway obstruction disease, 65 years of age or older. The test is in the morning 9 ~ 11 into
