The slow increase in heart rate which is observed in normal man submitted to heavy muscular exercise is due for a part to an activation of orthosympathetic cardiac activity which is blocked by beta antagonists. It is also explained by direct action of hyperthermia on the heart.
在进行剧烈肌肉运动的正常人中观察到的心率缓慢增加，部分原因是正位交感神经心脏活动的激活，这种激活可被β受体拮抗剂阻断。它也可由体温过高对心脏的直接作用来解释。
