[Show abstract][Hide abstract] ABSTRACT: 25 males and 5 females suffering from chronic obstructive bronchitis (COB) underwent transcutaneous diaphragmatic electrostimulation (TDE). As shown by central intrapulmonary hemodynamics, those patients who had no circulatory decompensation benefited from TDE. There was a decrease in the pulmonary hypertension, intensification of general hemodynamics, reduced tonicity of the pulmonary arteriolar bed, improvement of right ventricular function. In circulatory decompensation TDE may cause deterioration of right ventricular function, enhancement of circulation decompensation against unchanged pulmonary hypertension and pulmonary-arteriolar tonicity. The changes in pulmonary artery pressure, total pulmonary vascular resistance, pulmonary-arteriolar elasticity observed after a single TDE session may prompt the validity of further COB treatment according to the above regimen.

[Show abstract][Hide abstract] ABSTRACT: Central and intrapulmonary hemodynamic parameters were examined by direct and indirect methods in 46 patients with myocarditis (25 females and 21 males), which revealed diminished myocardial contractility, which was followed by a regular and significant pulmonary blood pressure and a reduction in the elastic properties of the pulmonary-arteriolar bed. Central and intrapulmonary hemodynamic changes are mostly associated with the development of hypodynamia and more rarely with that of the phase hemodynamic syndrome and more rarely with the volume overloading syndrome.
[Show abstract][Hide abstract] ABSTRACT: Hemodynamic studies by direct and indirect methods in patients with myocarditis have revealed that as pulmonary hypertension developed, right-ventricular myocardial contractility and pulmonary arteriolar bed elasticity were decreasing. High pulmonary hypertension and structural shifts in pulmonary artery wall reduced the volumic potentialities of the lesser circulation. The antiorthostatic test was found an important test for the detection of compensatory deposition potentialities of the lesser circulation vessels in myocarditis patients.

[Show abstract][Hide abstract] ABSTRACT: Radiocardiography and rheography of the pulmonary artery were used to examine impairments in hemodynamics and contractile function of the right ventricle in 40 patients with chronic obstructive bronchitis complicated with persistent hypertension. Right ventricular hemodynamic and contractile impairments were shown to be not equivalent with similar clinical and functional signs of pulmonary hypertension. This fact indicates that the use of special techniques is of practical value in the determination of right ventricular hemodynamics and myocardial contractility in patients with chronic obstructive bronchitis. Radiocardiography and rheography of the pulmonary artery are sufficiently reliable noninvasive techniques for examining the hemodynamics and contractile function of the right ventricular myocardium.
