[Comparative evaluation of the cardiac stroke and minute volumes by impedance cardiography and radiocardiography].

In 32 health subjects and 33 patients, mainly with acquired heart defects, the indices of central hemodynamics were determined, namely -- stroke and minute volume and their indices via impedance-cardiographic and radiocardiographic methods. A very good correlation was established between those indices, obtained via both methods. Impedance-cardiography is concluded to be a very convenient easily applicable method in determining cardiac hemodynamics, both in healthy subjects and cardiac patients with acquired heart defects.
