History of development of the method of measurement of duration of the preejection (DPE) period - characteristic of left ventricular (LV) contractility is presented. On the basis of physiological prerequisites a novel computerized method of DPE measu

Beat-by-beat evaluation of left ventricular contractility provides and insight to the current dynamics of cardiac control. In non-invasive studies, pre-ejection period is conventionally used as an index of contractility. Pulse waves of electrical imp

The impedance cardiography (ICG) is widely used for beat-to-beat noninvasive evaluation of the left ventricular stroke volume and contractility. It implies the correct determination of the ejection start and end points and the amplitudes of certain p

The histomechanical hypothesis of working hyperemia in skeletal muscle was verified by comparison of the dynamics and values of frog submaxillary muscle arterioles dilation under: 1) 4-Hz twitch contraction and 2) imitation of mechanical component of

Visible light, as usually used for intravital microscopy, causes dilatation of the arterioles of the denervated frog submaxillary muscle. The minimal effective intensity of illumination of the object was 15 lx. The degree of dilatation of the arterio

The effectiveness of two-dimensional correction in television angiomicrometry is examined. Attention is concentrated on correction of wall fronts of microvessels and dynamic unsharpness of blood cells in the microvascular system. It was shown experim

Low-frequency (about 4/sec) oscillatory displacements of resting fibers of the frog submaxillary muscle, leading to bending microdeformations of the arterioles located among them, cause considerable dilatation of them [3]. This phenomenon is evidence
