Multifaceted Left Bundle Branch Block: What Are the Mechanisms?

ABSTRACT: Understanding different mechanisms of aberrant conduction is critical to better evaluate the need for cardiac pacing. Aberrant conduction is caused by 4 distinct electrophysiologic mechanisms: phase 3 block, acceleration-dependent block, phase 4 block, and concealed transseptal conduction. This case offers a unique opportunity to review all aberrant conduction mechanisms in the same patient. (Level of Difficulty: Intermediate.).
