Abstract
Introduction: Right bundle branch block (RBBB) is one of the most common
electrocardiographic abnormalities that may lead to poor outcomes in patients
with cardiovascular diseases. Previous studies reported the impact of
idiopathic RBBB on several right ventricular systolic function variables. Thus,
the necessity of evaluating RBBB patients is more felt. This study aimed to
compare the evaluation of the right ventricular (RV) systolic function in
individuals with and without idiopathic right bundle branch block.
Materials and
Methods: In this comparative cross-sectional study,
52 patients with idiopathic RBBB and 60 normal individuals were enrolled. The
variables examined in this study were demographic information (age and gender)
and echocardiographic findings such as strain (longitudinal strain), strain
rate, right ventricular fractional area change (FAC), left ventricular ejection
fraction (LVEF), and mitral inflow.
Results: The global longitudinal strain, strain rate, and time to peak
(except the E wave index in the lateral wall) of the whole right ventricle and
the septal and lateral wall separately were significant (P <0.01). The mean
and standard deviation of the FAC index was statistically insignificant. The
LVEF index in both groups was in the normal range (LVEF<50%) and was
statistically insignificant. Mitral inflow was statistically insignificant.
Statistical analysis of the data was insignificant in terms of gender.
Conclusion: Subtle abnormalities can be seen in RV systolic function in
patients with idiopathic RBBB. Thus, this
individual group feels more need for regular clinical evaluation.
