title: [Left ventricular contractility studied by radionuclide ventriculography].
abstract: The general and regional contractility of the left ventricle was studied in 69 patients with chronic coronary heart disease (CHD) and in 10 practically healthy persons using the method of radionuclide ventriculography (RNVG). The contractility indicators in dynamic and static RNVG were correlated. A high degree of correlation was obtained between them as well as with the findings of radiopaque ventriculography. It was established that data processing with the help of a cardiosynchronizer is of high informative value, significant and can be used in RNVG variants thus making it possible to use the same program of processing. The frequency of the methods and mean dispersion of the results were assessed. Numerical values of the general and regional contractility in healthy persons and in patients with varying severity of chronic CHD were determined.
