Flynn等建立的小动物离体作功心脏是研究心脏功能最常用的实验标本,具有前负荷和后负荷可人为调节以及进行正常泵活动两大优点,在这种制备上可以记录多个泵功能和心肌力学等容相指标,但却不能测量记录心肌力学射血相指标以及收缩末期压力容积关系或压力直径关系(ESPVR或ESPDR)及其指标最大容积弹性模量(E_(max)),其原因是,这两种指标都须测量心室容积或心室径。小
Flynn and other small animals established by the heart to study the cardiac function of the heart is the most commonly used experimental specimens, with pre-load and afterload can be artificially adjusted and normal pump activity two major advantages in this preparation can record multiple pump functions And myocardial isovolumic indicators, but not recording and recording of myocardial ejection fraction and end-systolic pressure volume relationship or pressure-diameter relationship (ESPVR or ESPDR) and its index maximum volume elastic modulus (E_ (max)), the reason Yes, both measures must measure ventricular volume or ventricular diameter. small
