title: [Electrocardiographic and histomorphological changes in the myocardium of rats with Selye's experimental hypertension].
abstract: The authors described electrocardiographic and histomorphological changes in white rats with coarctation hypertention, induced by the method of Selye. The electrocardiographic changes were manifested as prologation of preauricular-ventricular conduction time, dislocation of the intermediate part ST to the isoelectrical line, low, negative or biphasic T-wave at the initial stages of the experiment, but after the thirthieth day there was a pathologic Q-wave, a reduced voltage of the steap curves and manifested left type of ECG in the majority of the experimental animals. Histomorphological and histochemical study on thmyocardium revealed in the beginning of the experiment mainly lesion changes, but sign of myocardial hypertrophy and manifested difuse and/or focal myocardial fibrosis on the 30th to the 90th day of the experiment.
