Bundle branch block and nonspecific intraventricular conduction delay prevalence using Chinese nationwide survey data.

ABSTRACT:

Objective

We aimed to determine the prevalence of and the factors associated with intraventricular conduction disturbance in the Chinese population.

Methods

Electrocardiographic data from 42,031 people were retrospectively analysed. The weighted prevalences of left bundle branch block (LBBB), right bundle branch block (RBBB), bifascicular block and nonspecific intraventricular conduction delay (NS-IVCD) were calculated. The independently associated factors were determined using logistic regression analysis.

Results

The weighted prevalence for Chinese people older than 45 years was 0.17% for LBBB, 2.16% for RBBB and 0.44% for NS-IVCD. The weighted prevalence for RBBB combined with left anterior fascicular block was 0.17%, and 0.05% for RBBB combined with left posterior
