About parasystole in children

Abstract

In recent years, there has been an increase in interest in parasystole in children, since this form of arrhythmia is much more common than expected. Parasystole is an independent type of arrhythmia with the activity of the ectopic center. Diagnosis of parasystole is possible only with an electrocardiographic study. ECG signs of parasystole are characterized by a variation of pre-ectopic intervals, the presence of a common time divider for interectopic intervals and confluent complexes. Parasystole is combined with various arrhythmias, but most often with extrasystole. Electrocardiographic diagnosis of parasystole in children is complicated by the irregularity of sinus rhythm and physiological characteristics of the rhythm frequency according to age groups. In practice, the differential diagnosis between parasystole and extrasystole is especially difficult and in some cases is possible only with the help of functional tests.
