Частота и характер нарушений ритма, проводимости и особенности микроструктурных аномалий сердца у детей и подростков с постмиокардитическими миокардиодистрофиями

Abstract

Various arrhythmias, that do not significantly affect the systemic hemodynamics, are detected in children with myocardiodystrophy: sinus tachycardia and bradycardia, rare, supraventricular extrasystoles, incomplete bundlebranch block. In case of postmyocarditic myocardiodystrophy predominance of heart blocks is observed, adverse prognostic arrhythmias are recorded more frequently: frequent, intervening, politopnye, group beats, allodromy, complex arrhythmias. Automatism function predominantly affects in patients with other dystrophies, often with the arrhythmias development. Minor anomalies of the heart are often found in children with myocardiodystrophy, the chords in the left ventricular cavity occur more often, both isolated and in combination with other minor anomalies.
