Normal Vectorcardiographic Parameters in Infants and Children

Abstract

Normal ranges of 32 parameters in vectorcardiography were determined in 200 healthy infants and children. The subjects were divided into 5 groups and results were compared in each group. Significant differences were found in 11 parameters. The differences were associated with a physiologically prominent right ventricular load in younger age groups. Therefore, age should be considered in evaluation of vectorcardiography.
