Disturbances of impulse formation and conduction may arise in the early stage of scleroderma, as a sign of cardiac involvement, termed "scleroderma heart". The incidence of various intraventricular conduction disturbances and their association with other disorders of cardiac rhythm were analysed in 193 scleroderma-patients by age. The presence of ventricular conduction abnormalities was found to carry an increased hazard of the production of disorders of atrioventricular conduction and of abnormal impulse formation. The patients were also followed up for deviation of the R axis in the frontal plane. Septal hypertrophy was found more frequently in patients with intraventricular conduction disturbances than in those free from disorders of this type.
在硬皮病早期可能会出现冲动形成和传导障碍，这是心脏受累的一种表现，称为“硬皮病心脏”。对193例硬皮病患者按年龄分析了各种室内传导障碍的发生率及其与其他心律失常的关联。发现存在心室传导异常会增加发生房室传导障碍和异常冲动形成的风险。还对患者进行随访，观察额面R轴偏移情况。与无此类障碍的患者相比，室内传导障碍患者中更常发现间隔肥厚。
