    Author: Guadalajara JF, Fishleder BL, Cornó A, Hladky M, Araujo J, Friedland C.
    Journal: Arch Inst Cardiol Mex; 1979; 49(2):188-99. PubMed ID: 443931.
    Abstract:
    When studying 141 normal persons of both sexes we checked acoustic phenomena and measured the sistolic intervals. We discuss here the presence of blowing anorganic phenomena and sounds III and IV among the general public. We develop equations of regression to correct the electromechanic sistole (QIIA) and the left ventricular ejection time (LVET) the registered values being different from those published by other researchers. Last of all we analyse semiology and the interpretation of the sistolic phases of the cardiac cycle using them in a routinary way and stressing its value and limitations, specially when used to get a better knowledge of the state of the myocardial functions.
