The daily Holter ECG monitoring and echocardiography were conducted in 61 men aged on the average 50.5...1.2 years with a diagnosis of stage II essential hypertension. 55.7% of the patients manifested episodes of painless depression of the ST segment. Such parameters as the patients' age, duration and intensity of arterial hypertension, the painful syndrome pattern did not afford revealing persons at high risk for instability of the ST segment of the ECG. Only initial disorders of the repolarization phase of the ECG at rest, so-called ECG with the signs of left ventricle hypertrophy with "strain" were in this respect of prognostic importance. 2/3 of the patients with the left ventricle mass exceeding 200 g manifested episodes of "silent" depression of the ST segment, with those episodes being encountered more frequently in left ventricle hypertrophy with an asymmetry index greater than or equal to 1.5.
