We present a case that demonstrates the rare occurrence of type 1 second-degree atrioventricular block (Wenckebach or Mobitz type 1 block) as a result of block in the infranodal conduction system. This extremely rare occurrence often predicts progression to complete heart block and necessitates cardiac pacing. It also demonstrates the value of an electrophysiological study and exercise stress testing to identify the level of block, predict prognosis, and plan a management strategy.
我们报告一例因结下传导系统阻滞导致罕见的1型二度房室传导阻滞(文氏或莫氏1型阻滞)的病例。这种极为罕见的情况常预示着会进展为完全性心脏传导阻滞,需要进行心脏起搏治疗。它还证明了电生理研究和运动负荷试验在确定阻滞部位、预测预后以及制定管理策略方面的价值。
