[Determination of the maximum speed of increase of pressure, the index and reserve of myocardial contractility as factors in hemodynamic studies of hypertension].
The authors' original non-invasive technique of determining the speed of pressure, elevation in the aorta, the index and reserve of myocardial contractility that reflects its contractile function was used in 80 persons (among them 25 normal individuals and 55 hypertonics). The main types of haemodynamic shifts noted in hypertension and its variants were described on the basis of simultaneous measurements performed by the above technique and by determinations of the cardiac output, speed of a pulse wave spreading and partial peripheral resistance. The suggested indices appeared to be the most sensitive ones permitting to detect the hypertensive type of the circulation of the initial stages of hypertensive disease.
