The effect of ischaemia of the sino-atrial node on cardiac vagal action was studied in anaesthetized dogs. The cut, cardiac end of the right vagus nerve was stimulated with a standard supramaximal stimulus every 10 s. The arterial supply to the sinoatrial node was occluded for periods of 1-3 min during this intermittent vagal stimulation. Vagal action on heart rate was potentiated during ischaemia of the sino-atrial node.
在麻醉犬中研究了窦房结缺血对心脏迷走神经作用的影响。每隔10秒用标准的超强刺激刺激右侧迷走神经切断后的心脏端。在这种间歇性迷走神经刺激期间，阻断窦房结的动脉供应1至3分钟。在窦房结缺血期间，迷走神经对心率的作用增强。
