[Improvement of ECG analysis in monitoring the electrical cardiac activity].

The goal of this work was to suggest a method for improving the efficiency of ECG analysis in measurements of the electrical cardiac activity. The suggested method is based on a solution of the inverse ECG problem. The algorithm for measuring the electrical cardiac activity includes storage of ECG signals from various sources in a database (the body and heart geometry are taken into account), determination of electrically active areas, and determination of the electrical activity at each point of the heart model surface.

Myocardial hypertrophy of the left ventricle during familial arterial hypertension.

In patients with familial arterial hypertension and their relatives preclinical signs of myocardial hypertrophy were observed before the formation of stably increased blood pressure. We evaluated echocardiographic sings of left ventricular myocardial hypertrophy in normotensive relatives of patients with arterial hypertension.
