Abstract：Objective To explore the characteristics of electrocardiogram(ECG) in F lead in diagnosing left bundle branch block and its complications.MethodsThe ECGs in F lead were retrospectively analyzed among 76 508 cases of healthy people so as to determine the occurrence of complete left bundle branch block. ResultsLeft bundle branch block was found in 49 cases(accounting for 0.064%), among whom were 19 cases(accounting for 38.78%) with true left bundle branch block and 20 cases(accounting for 40.82%) with complications. ConclusionThe characteristic of limb leads enables ECG in F lead to diagnose left bundle branch block at an early phase.
