Heart rhythm and conductive disturbances in first-year children: risk factors, clinical characteristics, outcomes

We had a first-year children comparative study with (n=38) and without (n=40) cardiac arrhythmias and we had a prospective follow-up examination of study group (n=28). We analyzed case histories, we examined this children with clinical and other methods. From prospective follow-up study we identify three risk groups of arrhythmia persistence and poor outcomes.
