- Activation of the heart normally begins in the sinoatrial node .
在正常情况下，心脏的活动始于窦房结。 - The sinoatrial node is located at the junction of the superior vena cava and the right atrium .
窦房结位于上腔静脉与右心房的交界处。 - Effect of exhaustive exercise on microstructure of sinoatrial node of rats
力竭运动对大鼠窦房结显微结构的影响 - In order to investigate the relationship between myocardium responsiveness and its firing dynamic states , bilateral vagotomy , m receptor blocking , acetylcholine ( ach ) perfusion and continuously autonomic nerve ending stimulating methods were employed to change the rabbit sinoatrial node ( sa ) firing dynamics . isoprenaline , noradrenalin , ach , sympathetic or vagal nerve ending stimulation was used individually to measure the sa responsiveness in different dynamic state
3 、窦房结在正常放电状态时，对0卫， 0人0石ug kg异丙肾上腺素的反应性均强于应用阿托品后，前后相比有显著差异（ p 0刀5 ） ；待阿托品作用部分消除后，窦房结对异丙肾上腺素的反应性也部分恢复。 - Above influences are conformed by central nervous system and transmitted to sinoatrial node by sympathetic and parasympathetic nerves . in physiological conditions the parasympathetic nerve modulation to sinoatrial node play more important roles than sympathetic nerve and is the main source of the heart rate variability
在正常完整机体，心交感及心迷走均对窦房结施加紧张性影响，但在安静状态下心迷走紧张性影响居主导地位且是产生心率变异性(指逐次心搏rr间期不断波动的现象)的主要原因之一。
