A study was made of the electrokymogram (EKG) of the left and the right ventricle of the heart in 54 patients suffering from toxic goiter chiefly with a marked clinical picture of the disease. Electrokymography permitted to detect enlargement of the ventricles. Excited pulsation of the ventricles with a rapid rise in systole and a sharp fall in diastole pointed to myocardial hyperfunction. Rapid and energetic contractions of the heart led to intensification of the oscillatory movements of the heart in the chest cavity, and to its rotation. A low-wave pulsation with small frequent waves of low amplitude pointed to a reduction of the contractile function of the myocardium; this was also indicated by the increase of the latent EKG time and the paradoxical movements at the beginning of systole. After the effective treatment the EKG of the ventricles showed almost no difference from the curves of healthy individuals. Changes in the character of the ventricular pulsation in toxic goiter were observed already at the early phase of the disease when some of the patients still displayed no changes in the ECG, and no X-ray data pointing to the affection of the heart were as yet evident. In the presence of phenomena of cardiac insufficiency the EKG objectively proved the presence of changes in the myocardium. The EKG data corresponded to the severity of the clinical picture of the disease. Electrokymography serves as a valuable method for analysis of the function of myocardium of the ventricles in toxic goiter.
对54例主要表现为明显临床症状的毒性甲状腺肿患者的心脏左右心室进行了心电图描记图（EKG）研究。心电图描记法能够检测到心室扩大。心室兴奋搏动，收缩期快速上升，舒张期急剧下降，表明心肌功能亢进。心脏快速有力的收缩导致胸腔内心脏振荡运动加剧，并使其发生旋转。低波搏动，伴有小而频繁的低幅波，表明心肌收缩功能降低；这也可由EKG潜伏时间延长和收缩期开始时的矛盾运动来表明。有效治疗后，心室的EKG与健康个体的曲线几乎没有差异。在毒性甲状腺肿疾病的早期阶段，当一些患者的心电图仍无变化，且尚无X线数据表明心脏受到影响时，就已观察到心室搏动特征的变化。在存在心脏功能不全现象时，EKG客观地证明了心肌存在变化。EKG数据与疾病临床表现的严重程度相符。心电图描记法是分析毒性甲状腺肿患者心室心肌功能的一种有价值的方法。
