与心率的增快或减慢密切相关的传导阻滞称频率依赖型传导阻滞,它可发生在房室交界处、左右束支、以及分支内.结间束传导阻滞近来亦有报道,但均为单纯3相或4相阻滞。笔者最近遇到1例二者兼有的病例。现报告如下。 Closely related to the increase or decrease of heart rate is called frequency-dependent conduction block, which can occur at the atrioventricular junction, the left and right bundle branches, and within the branch.The intercostal bundle block has also been reported recently, But they are pure 3-phase or 4-phase block. I recently encountered a case of both the two cases. The report is as follows.
