[Characteristics of external respiration function and pulmonary circulation in patients with ischemic heart disease complicated by disorders of intraventricular conduction].

The authors provide evidence on the condition of external respiration and hemodynamic shifts in the lesser and greater circulation in coronary patients with bundle-branch block; establish early objective quantitative criteria of the diagnosis of hemodynamic impairment arising in formation of the above blocks basing on ECG, phonocardiography, echocardiography findings; compare hemodynamic effects of single-dose nitrosorbide and corinfar in the above patients. Nitrosorbide and corinfar correct hemodynamics and external respiration, the former being more effective in normalizing the greater, while corinfar the lesser circulation.
