[Effect of the contractile function of the myocardium on the nature of hemodynamic reactions in patients with ischemic heart disease during Valsalva's test].
Application of contrast cineventriculography and probe of the left ventricle indicated that there was a relationship between the status of myocardial contractility, its function, some hemodynamic parameters, the severity of regional left ventricular wall contractility impairments and the nature of a hemodynamic response to Valsalva's test. Normal left ventricular contractility determined sinusoidal responses. Decompensated impairments of myocardial contractility gave rise to a square wave. A response represented as a nil ++super-elevation was caused by a moderate impairment of left ventricular contractility and, probably, by the absence of adequate vasoconstriction in the fourth phase of Valsalva's test.
