[Problems of so-called functional ECG changes].

It is reported on a 25-year-old African student with healthy heart in whom on account of an enlarged hepatologic diagnostics considerable changes of the ECG with repeated alteration between the ST-elevations and the T-negativations became manifest in the anterolateral BW-leads. In the otherwise inconspicuous findings functional changes of the ECG (early repolarization syndrome) with pronounced vegetative lability are concerned. The influence on the changes of the ECG by sympathicomimetics (isoproterenol test) may help to alleviate the diagnostics. In connection with diagnostic interventions the recognition and correct explanation of such ECG-findings is of decisive importance.
