- Taking cats as animal model , the postganglionic inferior cardiac sympathetic nerve activity is analyzed with DFA(detrended fluctuation analysis) to explored its fractality. 本文采用猫做为实验动物模型,运用去趋势波动分析的方法,对星状神经节后心下交感神经电活动的分形性质进行了分析。
- The hypothalamic stimulation-induced ventricular extrasystole (HVE) is mainly due to an increased activity of the cardiac sympathetic nerves caused by excitement of this area. 根据上述结果,可以认为兔下丘脑也存在着“防御反应区”,HVE主要是兴奋了防御反应区造成心交感活动亢进所致。

- Many findings suggest that sympathetic nerve sprouting could contribute to proarrhythmia substrate formation by promoting cardiac structural and electrical remodelling. 交感神经重构与心肌组织重构、电重构相互影响,可能是心律失常发生的基础。
- The cardiac sympathetic afferent reflex (CSAR), which is enhanced in the CHF state, contributes to an increase in sympathetic outflow in the CHF state. CHF时心交感传入反射(CSAR)的病理性增强是导致交感活动亢进的重要原因之一,在CHF发病机制中起到极其重要的作用。

- Conclusion Histamine is expressed in the cardiac sympathetic fibers from the guinea pig superior cervical ganglion and coexisted with norepinephrine. 结论 豚鼠颈上神经节投射到心脏交感神经纤维中有组胺的表达并与去甲肾上腺素共存。
- Stimulation of this area in hypothalamus could also induce an increase in cardiac sympathetic activity and ventricular extrasystoles. 在出现上述反应的同时可出现心交感活动亢进、产生室性期前收缩等心律失常。
