[Diagnosis of pulmonary hypertension with the aid of electrokymography].

Electrokymography was carried out in 198 patients with cor pulmonale and mitral defect with clinical signs of elevated blood pressure in the pulmonary circulation. The electrokymographic signs of pulmonary hypertension were developed, as well as those for the evaluation of the functional state of the myocardium of both ventricles. In making the diagnosis of elevated--pressure in the pulmonary artery system of special importance is the analysis of the electrokymogrammes of the pulmonary artery, right atrium and right ventricle, and the determination of the pulse wave speed along the pulmonary vessels. The study of the electrokymogrammes and their comparison with the clinical pattern permitted to classify all the electrokymographic criteria of pulmonary hypertension into true and relative ones, requiring verification. A differentiated analysis of the systolic and diastolic phases of the left and right ventricles was conducted. All the phases of the cardiac cycle were calculated with due regard of the contractions rate. The phase analysis permitted to assess separately the functional state of the myocardium of both halves of the heart. Electrokymography helped to reveal pulmonary hypertension that could be often diagnosed with its aid at an early stage. It permitted to diagnos an initial reduction of the contractile finction of the right ventricle.

[Combined method of rectopexy in rectal prolapse with the use of skin autoimplants].

During 1964-1973 twenty six patients were operated upon for grave rectal prolapse (6 patients after 1-2 unsuccessful operations elsewhere). The combined method of rectopexy by means of skin autoimplants after the technic suggested by B.A. Barkov was employed. All patients recovered and were completely rehabilitated, the follow-up being from 2 to 10 years. No recurrences were noted.
