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).

摘要

在75只健康兔中测定左心室收缩时间间期(STI)及其指标,以确定这些值的正常范围。分析中考虑了心率对这些参数值的影响。发现心率与QT间期(r = -0.8673)、总电机械收缩期 - QS2(r = -0.5557)、心音间期 - S1S2(r = -5696)、左心室射血时间 - LVET(r = -0.4745)、射血前期 - PEP(r = -2288)、等容收缩时间 - ICT(r = -0.2570)之间存在相关性。未发现心率与电机械延迟 - Q-1(r = -0.0226)之间存在相关性。
