The purpose of thee present work is to compare th value of two non invasive techniques: cycloergometer and dynamic ECG (Holter) in the diagnosis of ischaemic heart disease in subjects without basal ECG abnormalities and without clearcut clinical signs of coronary insufficiency. Twenty patients underwent both tests while in hospital. The ECG was continuously monitored for 24 hours according to the Holter method. In fifteen out of the twenty cases examined for results obtained with the two different techniques were in agreement; in three cases ischaemic ECG changes were seen only with the ergometer, in one only with the Holter and in one they were clearly present with the Holter, but were doubtful with the ergometric test. In our experience the Holter method should represent the first approach to studying patients suspected to be suffering from angina pectoris in view of its good sensitivity and of the absence of risk and contraindications. Maximal exercise test should be reserved to the patients in whom the Holter method has given negative results. The latter not only has a diagnostic value, but also "quantifies" the degree of ischaemia by recording symptomatic and asymptomatic ST depressions.
蹬车测力计和动态心电图（Holter）在诊断无基础心电图异常且无明确冠状动脉供血不足临床体征的受试者缺血性心脏病中的价值。20名患者在住院期间接受了这两项检查。根据Holter方法对心电图进行连续24小时监测。在接受检查的20例病例中，有15例通过两种不同技术获得的结果一致；3例仅在测力计检查时出现缺血性心电图改变，1例仅在Holter检查时出现，1例在Holter检查时明显出现，但在测力计检查时可疑。根据我们的经验，鉴于Holter方法具有良好的敏感性且无风险和禁忌证，它应是研究疑似心绞痛患者的首选方法。最大运动试验应保留给Holter方法结果为阴性的患者。后者不仅具有诊断价值，还通过记录有症状和无症状的ST段压低来“量化”缺血程度。
