对2例持续性心房静止患者进行了电生理和组织病理学检查。心内研究表明，心房停顿是由于心房不兴奋。这两例患者的H-V间期延长和H偏转持续时间与完全性右束分支阻滞有关，逸搏心律起源于房室交界处。组织学上，一位69岁的特发性心肌病患者的右心房明显纤维化，右心室纤维束。另一例40岁的女性围产期心脏病患者，右心室心肌中度变性。电子显微镜观察的结果也被提出。本文讨论了持续性心房静止时希氏束电图检查的重要性，以及这种病变的诊断标准和治疗。
Electrophysiological and histopathological examinations were carried out in 2 patients with persistent atrial standstill. Intracardiac studies revealed that atrial standstill was due to atrial inexcitability. It was demonstrated in both patients that prolongation of the H-V interval and the duration of H deflection was associated with complete right bundle branch block and that the escape rhythm was an A-V junctional origin. Histologically, marked fibrosis of the right atrium and fibrous strands in the right ventricle were demonstrated in a 69-year-old man with idiopathic cardiomyopathy. In another female patient with peripartum heart disease aged 40 years, there was moderate degeneration of the myocardium in the right ventricle. The results of electron microscopic observations are also presented. The importance of the examination of His bundle electrography in persistent atrial standstill and the diagnostic criteria and treatment of this lesion are discussed.
