Electrophysiologic investigations of the heart with the aid of transoesophageal atrium stimulation (extra-stimulus technique and overdriving stimulation) have been performed in 19 patients with primary hypothyroidism and a normal electrocardiogram in standard linkages. The control group comprised 34 healthy persons. In 68% of patients with hypothyroidism there have been stated a prolonged refraction time of the atrium-ventricular and intraventricular conductivity system while in the case of healthy persons an analogic type of changes has been observed only in 12%. Atrium overdriving stimulation has shown a decrease of the atrium-ventricular conductibility at a frequency below 130/min and in 74% of the patients with hypothyroidism the blocking assumed a shape of Wenckebach's periodic.
借助经食管心房刺激（额外刺激技术和超速驱动刺激）对19例原发性甲状腺功能减退且标准导联心电图正常的患者进行了心脏电生理研究。对照组包括34名健康人。68%的甲状腺功能减退患者出现房室和心室内传导系统的不应期延长，而健康人仅12%出现类似类型的改变。心房超速驱动刺激显示，频率低于130次/分钟时房室传导性降低，74%的甲状腺功能减退患者的阻滞呈文氏周期型。
