After intravenous application of 1 mg digoxin in a 28-year-old patient with condition after myocarditis by means of premature atrial individual stimulation a SA-block I. type II was observed. Also in extremely premature stimuli the post-extrasystolic pauses remained compensating. After atrial double and multiple stimulation--a new method for the calculation of the sinuatrial conduction time--totally irregular poststimulation pauses appeared, which were regarded as an expression of a sinoauricular node initial block. Other possibilities of explanation are discussed.
对一名28岁心肌炎后患者静脉注射1毫克地高辛，通过房性早搏单个刺激，观察到I型II度窦房阻滞。在极早的刺激时，代偿间歇仍为代偿性。在心房双重和多重刺激（一种计算窦房传导时间的新方法）后，出现完全不规则的刺激后间歇，这被认为是窦房结起始阻滞的一种表现。文中讨论了其他可能的解释。
