摘要：

ST-segment monitoring by Holter or by continuous 12-lead ECG-monitoring have prognostic value in unstable angina and myocardial infarction. However, pseudo-changes" due to changes in body position may cause problems during monitoring for indicators of silent ischemia. Therefore, ischemia-monitoring with continuous la-lead ECG was performed in 36 clinically stable patients in different body positions. Using the EGG in supine position as reference, ST-segment changes were usually small but reached significant levels in some patients, especially in the left lateral decubital position. However these deviations of the ST-segment seemed to arise under certain circum-stances, which are possible to recognize in the clinical setting.
