运动试验时,铊闪烁法是一能确定心肌灌注的非侵入性试验。本研究着眼于该方法调查静息性心绞痛病人的价值。病人与方法 66例病人因静息性心绞痛紧急入院,年龄均少于70岁。所有病人均安全完成了运动试验。试验结果阳性者:连续3个复合波的 ST 段水平或下斜压低≥1mm,或 J 点后80ms ST 段上斜压低≥1mm。若达到最大预期心率的95%而无诊断性ST 段改变则为阴性。若病人不能达到最大预期心率的85%,但也未出现 ST 段诊断性变化。则视为无结论。约于最大加压55.5MBq 前1min,在臂静脉注入 Thalidomide scintigraphy is a noninvasive test that determines myocardial perfusion during exercise testing. This study looked at the value of this method in investigating patients with resting angina. Patients and Methods 66 patients were admitted to hospital due to resting angina, all under the age of 70 years. All patients completed the exercise test safely. Test results were positive: ST-segment level or baroclinic depression ≥1mm for three consecutive concomitant waves or ≥1mm baroclinic depression on ST segment at 80ms after J point. Patients who achieved 95% of their maximum expected heart rate without negative diagnostic ST-segment changes were negative. If the patient does not reach 85% of the maximum expected heart rate, no diagnostic changes in ST segment occur. It is regarded as inconclusive.
