Abstract
Marked first-degree atrioventricular block with a PR interval ≥500 ms is rare, leading to unusual P-wave placement. In this case, the P waves immediately after the QRS waves complicated rhythm interpretation. Close attention to P-wave morphology and fused premature ventricular complexes can be important for a proper diagnosis.
摘要
PR间期≥500毫秒的显著一度房室传导阻滞较为罕见，会导致P波位置异常。在这种情况下，QRS波之后紧接着的P波使心律解读变得复杂。密切关注P波形态和融合的室性早搏复合波对于准确诊断可能很重要。
