Assessment of the character and incidence of electrocardiographic changes in children with simple obesity.

The studied group comprised 82 children with simple obesity. In the group the character and frequency of ECG changes in 12 conventional leads were analyzed. A correlation was established between the character and frequency of these changes and the degree of overweight and obesity duration. In children with simple obesity a considerable prevalence was observed of disturbances of sinus rhythm, impairment of intraventricular conduction and signs of left ventricular hypertrophy. The observed changes were more frequent in children with over 5 years of obesity duration. No correlation was demonstrated between the incidence of these changes and the degree of overweight.
