Abstract
Cardiac diseases in children continue to be an important cause of morbidity and mortality. Pediatric cardiomyopathies are rare but serious and often life-threatening conditions. Dilated cardiomyopathy is the most common cause of heart failure in children.
To date, no study has accurately characterized the frequency of arrhythmia in children with dilated cardiomyopathy. Recent studies believe that children with dilated cardiomyopathy are at higher risk for life-threatening arrhythmias than previously appreciated.
The aim of this prospective study was to assess the incidence and types of arrhythmias in children with dilated cardiomyopathy, and to high-lighten the possible attributable risk factors.
This study was conducted in a period of three years (Dec. 2012-Dec. 2014) on all children suffering from dilated cardiomyopathy who were attending the cardiology clinic in Alexandria University Children’s Hospital.
The following data were collected from all patients enrolled in this study:
• Demographic data including; sex, presenting age, age at diagnosis of DCM, and duration of disease.
• Diagnostic echocardiography and presenting symptoms at time of diagnosis; syncope/near syncope, palpitation, dyspnea, chest pain, dizziness, or orthopnea.
• Previous hospitalizations and medications received and all cardiac medications prescribed to those patients.
