In order to assess the involvement of the cardiopulmonary receptors in the regulation of the coronary circulation, changes in coronary resistance produced by the application of a -10 mmHg pressure to the lower body were studied in 6 healthy subjects and 6 patients with arterial hypertension and left ventricular hypertrophy. The results show that the inhibition of the ventricular receptors significantly increases coronary resistance and that this reflex response is eliminated in hypertensive patients with ventricular hypertrophy.

为了评估心肺感受器在冠状动脉循环调节中的作用，对6名健康受试者和6名患有动脉高血压及左心室肥厚的患者进行了研究，观察了向下半身施加-10 mmHg压力时冠状动脉阻力的变化。结果表明，心室感受器的抑制显著增加冠状动脉阻力，且这种反射反应在患有心室肥厚的高血压患者中消失。结果表明，心室感受器的抑制显著增加冠状动脉阻力，且这种反射反应在患有心室肥厚的高血压患者中消失。
