Abstract
- Action potentials were recorded from fibres in the right cervical vagus, the receptor endings of which were localized to the endocardial surface of the superior vena caval-right atrial junction.2. Stretching the junction between the superior vena cava and the right atrium without obstructing venous return caused an increase in the discharge of these fibres. This increase in impulse frequency was similar to that caused by small changes in mean right atrial pressure (range 0-13.5 cm H(2)O).3. This evidence supports the earlier suggestion that stimulation of the right atrial receptors by stretching the superior vena caval-right atrial junction causes a reflex increase in heart rate.
摘要
从右侧颈迷走神经的纤维记录动作电位，其感受器末梢定位于上腔静脉-右心房交界处的心内膜表面。
在不阻碍静脉回流的情况下拉伸上腔静脉与右心房之间的交界处，会导致这些纤维的放电增加。这种冲动频率的增加与平均右心房压力的微小变化（范围为0 - 13.5厘米水柱）所引起的增加相似。
这一证据支持了早期的推测，即通过拉伸上腔静脉-右心房交界处来刺激右心房感受器会导致心率反射性增加。
