目的观察多种环境因素改变对心肌缺血家兔心电活动的影响。方法将家兔随机分成单纯心肌缺血组、缺血低氧高温组、缺血低氧组、饥饿缺血组、缺血低氧高温饥饿组、单纯饥饿组、单纯低氧组和单纯高温组共8个组,并设对照组进行比较,每组10只。把各组分别放入相应的环境中,经实验30min后测定各组的心电图(Ⅱ导联)变化并与对照组比较。结果不同环境因素变化均发现所有的实验动物的心电活动都有不同程度的改变,尤其心肌缺血低氧高温饥饿的动物有进一步加重的表现。结论多因素的环境变化对心肌缺血家兔心电活动都有一定的影响。
Objective To observe the effect of various environmental factors on the cardiac activity of myocardial ischemia in rabbits. Methods Rabbits were randomly divided into three groups: simple myocardial ischemia group, hypoxic hypoxic ischemic group, ischemic hypoxia group, starvation ischemic group, ischemic hypoxic hyperthermia starvation group, starvation alone group, hypoxia group and hyperthermia group A total of eight groups, and set the control group for comparison, each group of 10. The groups were placed in the corresponding environment, after the experiment 30min after the determination of each group of ECG (Ⅱ lead) changes and compared with the control group. Results The change of different environmental factors found that all the experimental animals had varying degrees of changes in their electrocardiographic activities. In particular, the animals with hypoxia, hypoxia, and starvation were further aggravated. Conclusion The multi-factor changes of environment have certain influence on the cardiac activity of myocardial ischemia in rabbits.
