The criteria for left bundle branch block have gained growing interest in the last few years. In this overview, we discuss diagnostic and prognostic aspects of different criteria. It was already shown that stricter criteria, including longer QRS duration and slurring/notching of the QRS, better identify responders to cardiac resynchronization therapy. We also include aspects of ST/T concordance and discordance and vectorcardiography, which could further improve in the fine-tuning of the left bundle branch criteria.
在过去几年中,左束支传导阻滞的诊断标准越来越受到关注。在本综述中,我们讨论了不同标准的诊断和预后方面。已经表明,更严格的标准,包括更长的QRS时限以及QRS波的顿挫/切迹,能更好地识别心脏再同步治疗的反应者。我们还纳入了ST/T同向和异向以及向量心电图方面的内容,这可能会在左束支传导阻滞标准的微调方面进一步改进。
