Abstract

Right bundle branch block is an electrocardiographic phenomenon with specific criteria.Currently, two specific forms of right bundle branch block are acknowledged, a proximal and a distal variant. A vast array of pathologies can cause proximal, distal or even combined forms of right bundle branch block.IN THIS STUDY IT IS SUGGESTED THAT A THIRD TYPE OF RIGHT BUNDLE BRANCH BLOCK EXIST: one caused by a subaortic muscular tendon in the left ventricle, leading to an increased velocity of conduction in the left ventricle, with a resultant "relative" right bundle branch block. It is concluded that it is necessary (and time) to take a closer look at endoventricular structures in the assessment of structural causes of right bundle branch block.

摘要

右束支传导阻滞是一种具有特定标准的心电图现象。目前，公认右束支传导阻滞有两种特定形式，即近端型和远端型。大量病理情况可导致近端型、远端型甚至混合型右束支传导阻滞。本研究提示存在第三种类型的右束支传导阻滞：由左心室主动脉下肌性腱引起，导致左心室传导速度加快，继而出现“相对”性右束支传导阻滞。得出的结论是，在评估右束支传导阻滞的结构原因时，有必要（且时机已到）更仔细地观察心室内结构。
