  • Title: [The mechanism of the occurrence of segmental stress nonuniformities in the left ventricle during disordered excitation processes].

    Abstract:
    Intramural tension of the heart left ventricular wall and top, intracavity pressure and the ECG were measured in anesthetized dogs. Appearance of a ventricular excitation centre was shown to cause a tension in one of the segments and its simultaneous drop in another one. The intracavity pressure could remain unchanged due to the mechanism of complete compensation. Conditions of appearance, quantitative and qualitative estimation of sizes and geometry of zones of abnormal contractions in the segments, were determined.
