Correctly diagnosing left bundle branch block (LBBB) is fundamental, as LBBB occurs frequently in heart failure and may trigger a vicious cycle of progressive left ventricular dysfunction. Moreover, a correct diagnosis of LBBB is pivotal to guide cardiac resynchronisation therapy. Since the LBBB diagnostic criteria were recently updated by the European Society of Cardiology (ESC), we assessed their diagnostic accuracy compared with the previous ESC 2013 definition. We further discuss the complexity of defining LBBB within the context of recent insights into the electromechanical pathophysiology of LBBB.
正确诊断左束支传导阻滞(LBBB)至关重要,因为LBBB在心力衰竭中频繁出现,可能引发左心室功能进行性恶化的恶性循环。此外,正确诊断LBBB对于指导心脏再同步治疗至关重要。由于欧洲心脏病学会(ESC)最近更新了LBBB的诊断标准,我们评估了其与ESC 2013年之前定义相比的诊断准确性。我们还结合最近对LBBB机电病理生理学的认识,进一步讨论了定义LBBB的复杂性。
