SUMMARY
This study is based on the Reykjavík Study, a long-
term prospective cardiovascular survey including a
representative population of 9.135 men and 9.627
wornen, 33-79 years old, who were invited to
participate in a cohort study during the years 1967-
91.
Right bundle branch block (RBBB) was found in
126 men and 67 women. The prevalence increased
with age, from 0% among men and women 30-
39 years of age to 4.1% (men) and 1.6% (women)
75-79 years old. The incidence increased with
age among men and women. In men younger
than sixty RBBB had a significant relation to
hypertension (p<0.05), elevated fasting blood
glucose (p=0.05) and increased heart size (p<0.05).
In men with RBBB regardless of age, association
was found with ischemic heart disease (p<0.05),
arrhythmias (p<0.001) and bradycardia (p<0.01).
Higher mortality from heart disease (p<0.01) was
found in men with RBBB compared to the control
population. This was not significant when risk
factors of heart disease were taken into account
by multivariate Cox analysis. There was relation
(p<0.05) between hypertension and RBBB in
women younger than sixty.
RBBB in women younger than sixty is often
associated with hypertension and in men younger
than sixty RBBB is often associated with an
underlying cardiovascular disease, hypertension,
cardiomegaly and elevated blood glucose.
