The sinus arrhythmia of the human heart was investigated in its relation to the tidal volume under resting conditions in the course of the day, in voluntarily changed tidal volume, under atropine medication and during physical work. In resting conditions it was found that nearly 40% of the sinus arrhythmia is of respiratory origin, and that no respiratory influence is demonstrable any longer at sufficient doses of atropine. Under physical load, the sinus arrhythmia is diminished in spite of the enlarged tidal volume. In this case, an additional smoothing influence to the sinus arrhythmia has to be assumed.
在一天中的静息状态下、在自主改变潮气量时、在使用阿托品药物期间以及在体力劳动期间，对人体心脏的窦性心律失常与潮气量的关系进行了研究。在静息状态下发现，近40%的窦性心律失常起源于呼吸，并且在足够剂量的阿托品作用下不再显示出呼吸影响。在体力负荷下，尽管潮气量增大，但窦性心律失常仍会减弱。在这种情况下，必须假定对窦性心律失常还有一种额外的平滑作用。
