A study of Electrocardiographic pattern of normal school children in Palakkad District of Kerala
Journal Title: Pediatric Review: International Journal of Pediatric Research - Year 2016, Vol 3, Issue 11
Abstract
Background: Electrocardiography is a simple, non-invasive and relatively cheap investigative tool used for cardiac evaluation. However, there are limited electrocardiographic studies of Indian children. These differences may also be seen in children, hence, the need to develop local reference values. Methods: This was a cross-sectional study on selected 450 subjects. An 12 lead ECG was measured on all subjects. Results: There were two hundred and twenty boys (48.3 %) and two hundred and thirty girls (51.7 %). The mean heart rate decreased with increasing age. R wave amplitudes were higher in the left precordial leads, in keeping with left ventricular dominance. Mean values were higher in males than females in the three age-groups in most of the precordial and limb leads. In V4R, V2, andV3 highest mean R wave voltages of 0.5+0.1 mV, 1.4+0.3 mV and 1.4+0.2 mV were recorded in the 5-7-year-old. While in V5, and V6 the mean R waves were higher in the 12-15-year-old age-group (3.7+ 0.5 mV and 2.5+0.4 mV respectively). The S-Waves showed progressive decrease in its amplitude on the left precordial leads with increasing age. Conclusion: The mean values in heart rate, QRS duration, PR interval, P wave amplitude showed higher amplitudes in males. Similarly higher amplitudes of R-waves in male children were recorded in precordial leads V2, V3, V5 and V6 in the three age-groups.
