1953年,Cabrera和Friedlad 首先提出完全性左束支阻滞(LBBB)时,V3、V4导联S波升肢上出现的切迹(至少0.05s),是诊断伴有LBBB的前间隔心肌梗死的十分可靠的指标,其敏感性、特异性均为91%.

After pacing,the mean QRS duration was significantly shorter during RVS pacing than during RVA pacing(107.71±20.31 vs.140.88±23.68 ms,P＜0.01). No patient emerged left bundle branch block(LBBB)during RVS pacing.
与心尖部起搏相比,右室间隔上部起搏QRS波较窄(107.71±20.3l vs.140.88±23.68ms,P＜0.01),无新发完全性左束支阻滞病例,对照组则由术前6例增加至21例,P＜0.01。
