| 摘 要： | 观察30只家兔在心率固定情况下，改变缺血范围对心肌缺血早期室颤阈（VFT）、颈动脉血压和血浆去甲肾上腺素含量的影响以及切断双侧迷走神经后，于上述情况下VFT的变化，结果表明改变心肌缺血范围可影响VFT值；但与心率、血压、血浆去甲肾上腺素水平以及迷走神经状态无关 ，提示心肌缺血早期的室颤和缺血范围有关。

| Abstract: | The effect of early changing stage ischemic size on ventricular fibrillation thresh old(VFT), blood pressure and plasma noradrenaline concentration was observed in 30 rabbits with constant heart rate and excition of vagus in some animals. The result suggests that: VFT can be influenced by changing myocardial ischemic size; but the influence has no relation to heart rate, blood pressure, plasma noradrenaline and vagus. The result points out that the size of early stage myocardial ischemia has relation to the occurrence of ventricular fibrillation. |
