INTRODUCTION
About one-third of patients undergoing cardiac resynchronization therapy because of left bundle branch block (LBBB) and heart failure do not improve. Strauss et al. have developed strict criteria to more accurately define complete LBBB in this patient group. The aim of this study was to investigate the prevalence of the manual application of the Strauss criteria for LBBB (QRS ≥ 140 ms in men, ≥ 130 ms in women, along with mid-QRS notching/slurring) in consecutive patients who have been diagnosed with LBBB by the automated Glasgow criteria (QRS ≥ 120 ms).
METHOD
In 158 consecutive patients (78 females) diagnosed with LBBB according to the automated Glasgow criteria, the manual Strauss criteria were applied.
RESULTS & CONCLUSION: A majority of patients (87%) diagnosed with LBBB using the Glasgow criteria were positive for the Strauss criteria. In 70% (13/20) of the cases of disagreement the reason for disagreement was short QRS duration.
引言
因左束支传导阻滞（LBBB）和心力衰竭接受心脏再同步治疗的患者中，约三分之一病情未改善。施特劳斯等人制定了严格标准，以更准确地界定该患者群体中的完全性LBBB。本研究旨在调查在连续的、已通过自动格拉斯哥标准（QRS≥120毫秒）诊断为LBBB的患者中，手动应用施特劳斯LBBB标准（男性QRS≥140毫秒，女性≥130毫秒，同时伴有QRS波峰切迹/模糊）的情况。
方法
对158例根据自动格拉斯哥标准诊断为LBBB的连续患者（78例女性）应用手动施特劳斯标准。
结果与结论
使用格拉斯哥标准诊断为LBBB的大多数患者（87%）符合施特劳斯标准。在70%（13/20）存在分歧的病例中，分歧原因是QRS持续时间短。
