Abstract
- In anaesthetized dogs, distension of balloons so as to stimulate atrial receptors resulted in a reflex increase in heart rate. 2. Successive distensions of one, two and three balloons positioned in the left upper and middle pulmonary vein-atrial junctions and in the left atrial appendage resulted in a progressive increase in the magnitude of this response. 3. It is concluded that the magnitude of the increase in heart rate is related to the extent of receptor area stimulated.
摘要
- 在麻醉犬中，使球囊扩张以刺激心房感受器会导致心率反射性增加。2. 依次扩张位于左上和中肺静脉-心房交界处以及左心耳的一个、两个和三个球囊，会使这种反应的幅度逐渐增加。3. 得出的结论是，心率增加的幅度与受刺激的感受器面积大小有关。
