1985年我们在对潘生丁试验(简称DP-T)研究的基础上,设计了潘生丁踏车复合试验(简称复合试验),即在踏车运动试验之前,先静注一定量潘生丁(DP),通过对“冠心病心绞痛”、“可疑冠心病”、“健康人”共3组128人的试验研究,初步表明复合试验的敏感性明显高于单项潘生丁或踏车试验, In 1985 we based on the study of dipyridamole (referred to as DP-T), based on the design of the dipychia treadmill compound test (referred to as compound test), that is, before the treadmill exercise test, a certain amount of intravenous injection of dipyridamole (DP) The experimental study of 128 patients in 3 groups of “coronary heart disease angina pectoris”, “suspicious coronary heart disease” and “healthy person” initially showed that the sensitivity of compound test was significantly higher than that of single dipyridamole or treadmill test,
