潘生丁静滴会选择性地显著扩张冠状动脉。虽然~(201)铊～潘生丁试验阳性不一定表示有心肌缺血,但曾经建议将它作为探测冠状动脉疾病的一种激发试验。二维超声心动描记监护和潘生丁静滴联合应用的理论基础为冠状动脉显著狭窄时潘生丁会引起心内膜下缺血。
Dipyridamole intravenous infusion will significantly expand the coronary artery selectively. Although the ~ (201) thallium ~ dipyridamole test positive does not necessarily indicate myocardial ischemia, it has been suggested as an excitation test to detect coronary artery disease. The rationale for the combined use of two-dimensional echocardiographic monitoring and dipyridamole infusion is that dipyridamole causes subendocardial ischemia when stenosis of the coronary arteries is significant.
