Gammacardiographic and ballistocardiographic comparison of indices of central haemodynamics and the myocardial contractile functional state in patients with coronary heart disease.

A complex ballistocardiographic and gammacardiographic investigation was carried out in 62 patients with coronary heart disease; ballistocardiographic and gammacardiographic indices have been compared. We established pathologic ballistocardiographic changes, which indicate a disturbance of the myocardial contractile function. Considerable changes of central haemodynamics, studied by means of gammacardiography, were recorded. There is a relationship between ballistocardiographic indices of the myocardial contractile function and radiocardiographic indices of central haemodynamics.
