50 patients, 20 without heart disease and 30 with coronary heart disease (CHD), were studied by kinetocardiography (KCG), before and after administration of isoproterenol (initial dose 2 microgram/min, maximum dose 6 microgram/min). In the control subjects the KCG was unaffected by the drug. In contrast, in most of the patients with CHD isoproterenol induced the appearance or the increase of paradoxical systolic bulges, which are regarded as the expression of ventricular dyskinesia resulting from isoproterenol-induced transient regional ischemia. This test is recommended as a valuable noninvasive method for the diagnosis of ischemic ventricular dyskinesia.
对50例患者进行了心动力学描记法（KCG）研究，其中20例无心脏病，30例患有冠心病（CHD），在给予异丙肾上腺素（初始剂量2微克/分钟，最大剂量6微克/分钟）之前和之后进行观察。在对照组受试者中，KCG不受该药物影响。相比之下，在大多数冠心病患者中，异丙肾上腺素诱发了矛盾性收缩期膨隆的出现或增加，这被认为是异丙肾上腺素诱发的短暂局部缺血导致心室运动障碍的表现。该试验被推荐为诊断缺血性心室运动障碍的一种有价值的非侵入性方法。
