[The nature of the changes in the repolarization complex of the ECG in patients with arterial hypertension and left ventricular hypertrophy]. / O kharaktere izmenenii repoliarizatsionnogo kompleksa EKG u bol'nykh arterial'noi gipertoniei s gipertrofiei levogo zheludochka.

Altogether 58 patients suffering from arterial hypertension (AH) were examined. The patients with left ventricular hypertrophy (LVH) and changes in the ST-T demonstrated a high correlation between an increase of the end systolic tension (EST) and interval elongation and the minimal size of the left ventricle before mitral valve opening. These data point to the development of "high-stressful LVH" which is accompanied by a non-proportional increase of EST, subendocardial ischemia of the myocardium (changes in the ST-T) and derangement of diastolic heart function.
