Background- Bronchiolitis is one of the common respiratory infections of infancy and is most commonly caused by respiratory syncytial virus (RSV). This study was conducted to find the incidence of myocarditis and cardiac dysrrhythmia in RSV bronchiolitis.
Methods- During the winter and spring of 1999-2001, infants admitted with bronchiolitis to our department were studied. ECG was taken at time of admission and discharge. After RSV was determined as the etiologic agent by IFA, 50 infants were chosen for the study.
Results- There were ECG changes in 19 cases, but persistent changes fitting criteria of myocarditis were present in three cases. Statistically and in comparison with the control group, the incidence of myocarditis in RSV bronchiolitis was not significant (p= 0.0546).
Conclusion- The findings of this study show that while ECG is beneficial in bronchiolitis, persistent specific changes can be helpful in the diagnosis of clinical and subclinical myocarditis
