  • Title: Myocardial contractility in healthy rabbits.
    Author: Goch JH.
    Journal: Acta Physiol Pol; 1980; 31(5):485-91. PubMed ID: 7234433.
    Abstract:
    In 75 healthy rabbits the systolic times intervals (STI) and their indexes of the left-ventricle were determined for establishing the normal range of these values. In the analysis the effects of the heart rate on the values of these parameters were taken into account. A correlation was found between the heart rate and the QT interval (r = -0.8673), total electromechanical systole - QS2 (r = -0.5557), heart sounds interval - S1S2 (r = -5696), left ventricular ejection time - LVET (r = -0.4745), pre-ejection period - PEP (r = -2288), isovolumic contraction time - ICT (r = -0.2570). No correlation was found between the heart rate and the electromechanical delay - Q-1 (r = -0.0226).
