[The functional status of the left ventricle in normal conditions. Results of multiphase x-ray contrast left ventriculography]. / Funktsional'noe sostoianie levogo zheludochka v norme. Rezul'taty mnogofaznoi rentgenokontrastnoi levoi ventrikulografii.

The main functional characteristics of the left ventricle (LV) were defined using a method of multiphase radiopaque left ventriculography. Three groups of indices of LV function (energetic LV indices, indices of chamber diastolic function, and indices of local motion of the LV walls in the course of a complete cardiocycle) were standardized in healthy persons. An original algorithm of analysis of local LV myocardial contractility was used. A combined approach to interpretation of results of this method was worked out. A standard set of indices, reflecting LV function, was defined. Standardized values of these indices, necessary for an effective use of this method, were obtained.
