Prevalence of manual Strauss LBBB criteria in patients diagnosed with the automated Glasgow LBBB criteria. Annals of Noninvasive Electrocardiology published by Wiley Periodicals LLC.Īlmer, J. The prognostic impact of LBBB and NSIVCD was affected by the definition of the conduction disorder.īundle branch block electrocardiography intraventricular conduction delay population study prognosis. Other IVCDs had no significant impact on prognosis. In a population study with long-term follow-up, NSIVCD and Minnesota definition of LBBB were independently associated with CV mortality. Families and physicians often wonder what the termsintraventricular conduction delay (IVCD) or incomplete right bundle branch block (IRBBB) or rsR’ on an electrocardiogram mean and what to do with the information. The presence of R-R' pattern was not associated with any adverse outcome. While right bundle branch block, left anterior fascicular block and incomplete bundle branch blocks were associated with seemingly higher mortality, this was no longer the case after adjustment for age and sex. Subjects with NSIVCD were associated with twofold to threefold increase in CV mortality depending on the definition. 308) for the Strauss' definition of LBBB. After controlling for known clinical risk factors, the hazard ratio for CV death, compared with individuals without IVCD, was 1.55 for the Minnesota definition of LBBB (95% confidence interval 1.04-2.31, p =. For left bundle branch block (LBBB) and non-specific IVCD (NSIVCD), two different definitions were used.ĭuring 16.5 years' follow-up, 1,309 of the 6,299 subjects (20.8%) died and of these 655 (10.4%) were cardiovascular (CV) deaths. We studied long-term prognostic impact and the association with comorbidities of eight IVCDs in a random sample of 6,299 Finnish subjects (2,857 men and 3,442 women, mean age 52.8, SD 14.9 years) aged 30 or over who participated in the health examination including 12-lead ECG. Previous population studies have presented conflicting results regarding the prognostic impact of intraventricular conduction delays (IVCD).
