In cats bilateral sympathectomy or administration of reserpine results in a marked reduction in concentration of myocardial catecholamines. The contractility of papillary muscles from such animals is significantly less than that of muscles from untreated animals. These findings demonstrate the importance of normal levels of myocardial catecholamines in the maintenance of normal cardiac contractility.
在猫身上，双侧交感神经切除术或给予利血平会导致心肌儿茶酚胺浓度显著降低。来自此类动物的乳头肌收缩力明显低于未处理动物的肌肉收缩力。这些发现证明了心肌儿茶酚胺正常水平对维持正常心脏收缩力的重要性。
