undergoing pacemaker implantation with no prior history of heart failure (HF), the presence of left bundle branch block (LBBB) has been identified as an independent predictor of HF-related death or hospitalization, while the prognostic significance of right bundle branch block (RBBB) remains ...
The increased risk of death was also present when LBBB (HR 1.121, 95% CI 1.042–1.207) and RBBB (HR 1.187, 95% CI 1.045–1.348) were considered individually. There was no difference in risk between LBBB and RBBB (P for interaction = 0.533). Other outcomes including sudden death, ...

Study popula- tion, cases of QTc-prolongation, formula to correct for heart rate, cut-off values of QTc-prolongation and the statistically significant risk factors associated with QTc- prolongation were evaluated. The level of evidence was determined based on the level of significance in the ...
[The incidence, clinical characteristics and prognostic significance of a left bundle-branch block associated with an acute myocardial infarct]. To assess the current incidence and meaning of left bundle-branch block associated with acute myocardial infarction we studied 1,239 patients consecutively... ...
All statistical tests were 2-tailed, and a P value <0.05 was considered as the threshold for statistical significance. Statistical analyses were performed using R version 3.4 (R Foundation for Statistical Computing) equipped with the MatchIt package. Considering a 10% frequency of moderate or great...
