When immersed in plain water at 40 degrees C, normal young adults experience an important increase in the heart rate. beta adrenergic receptor blockade by propranolol (40 and 80 mg) reduces this tachycardia by 25%. The increase in the heart rate depends on orthosympathetic stimulation, on parasympathetic inhibition and on a Q10 effect related to the blood temperature acting on the sino-auricular node.
当正常年轻人浸入40摄氏度的清水中时，心率会显著增加。普萘洛尔（40毫克和80毫克）对β肾上腺素能受体的阻断可使这种心动过速降低25%。心率的增加取决于交感神经刺激、副交感神经抑制以及与作用于窦房结的血液温度相关的Q10效应。
