Example Sentences:
(1) It is shown that the polycrotic pulse form is characteristic hyperactivity of the sympathetic nervous system with the hypertonic, as well as the hypotonic forms of manifestation.
Sphygmogram
Definition:
(n.) A tracing, called a pulse tracing, consisting of a series of curves corresponding with the beats of the heart, obtained by the application of the sphygmograph.
Example Sentences:

(4) By means of Ecg, Pcg, carotid-sphygmogram and radiological findings, pathogenesis, pathophysiology as well as the morphological basis of this disease is illustrated.
(5) Changes in the arterial wall were noted in 85% of the 14 patients in whom carotid sphygmograms were recorded.
(6) The idea of the genesis of the carotid sphygmogram from the kinetocardiogram (GS-KCG) was developed on the basis of the analysis of the KCG and carotid-sphygmographic (CSG) pattern obtained in 10 young healthy adults.
(7) His clinical studies were done without the benefit of a sphygmomanometer but with the aid of a quantitative sphygmogram that he had initially developed while a medical student.
(8) The changes in the second segment and the appearance of the anacrotic segment determine the peculiarities of the sphygmograms that are typical for aortic stenosis.
(9) The differential and volume sphygmograms were recorded in the radial artery.
(10) Within the first week, all of the continuity solutions showed significant sphygmograms with a regular vascularization on the layer, this period of time concurred with the complete granulation phase of the ulcus.
(11) After a five-minute stoppage of the circulation, the following characteristic features of the differential sphygmogram were observed: 1) the differential curve assumed the shape of a triangle with a broad base; 2) the amplitudes of all wave components decreased, the B wave disappeared, the V2 wave was minimal, and the t2 time considerably extended.
(12) From this hypothesis and from the existence of a reflection wave starting at the aorta, the concept of the genesis of the sphygmogram from the kinetocardiogram was developed: the deformation starts at the aorta, is directed to the apex, is there reflected and propagated to the carotid artery.
(13) The sphygmogram with maximum amplitude was called optimum sphygmogram (OS) and its corresponding CP called optimum counter-pressure (OCP).

(18) In both groups significant quantitative differences in the sphygmograms were found which are indicative for reduced distensibility and indirectly for the degeneration of the arterial wall.
(19) An own procedure of quantitative analysis of the carotid sphygmogram is described.
(20) The frequency spectra of modulus and phase of the input impedance (Zin) of large human arteries (abdominal aorta, femoral and subclavian arteries) were computed from transcutaneously recorded, uncalibrated pressure and flow pulses picked up as sphygmograms and Doppler flow velocity pulses, respectively.
