ABSTRACT
Cardiac arrhythmias are significant risk factors for morbidity and mortality in children and adolescents with heart failure. Arrhythmias may result in diverse clinical symptoms, adversely affect ventricular function and have prognostic implications. However, conventional treatments for cardiac arrhythmias may not favorably or even adversely influence the clinical course of the disease process in heart failure patients. Therefore, decisions regarding the evaluation and
treatment of arrhythmias must consider both hemodynamic and electrophysiologic factors.
