Abstract
The article summarizes essential data concerning the most frequent heart rhythm disorders in children, focusing both on outpatient and hospital management. A major part of the article refers to differential diagnosis and treatment of supraventricular tachycardia, representing the most frequent symptomatic rhythm disorder in children, often requiring relatively urgent therapeutic intervention.
The chapter devoted to ventricular tachycardia focuses mainly on hereditary arrhythmia syndromes, especially the long QT syndrome. Finally, in the bradycardia section, complete atrioventricular block is discussed in more details.
