The atrioventricular conduction time (P-R interval) was determined in 189 women and 90 men with rheumatoid arthritis (RA). Only three women and one man were found to have pathological prolongation of the P-R interval. However, a significant prolongation of the P-R interval, within normal range, was seen in women with RA compared with healthy controls. Apart from the relation to radiographically enlarged heart, prolonged P-R interval showed no association with other signs of RA and had no prognostic implications in the follow-up period (mean 5.4 years). Current chloroquine therapy delayed the atrioventricular conduction while corticosteroids accelerated it.
在189名患有类风湿性关节炎（RA）的女性和90名患有类风湿性关节炎的男性中测定了房室传导时间（P-R间期）。仅发现3名女性和1名男性的P-R间期病理性延长。然而，与健康对照相比，RA女性患者的P-R间期虽在正常范围内但有显著延长。除了与影像学显示的心脏增大有关外，P-R间期延长与RA的其他体征无关联，且在随访期（平均5.4年）无预后意义。目前的氯喹治疗会延迟房室传导，而皮质类固醇则会加速房室传导。
