These effects have not yet been studied in detail in LBW children.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Fifty LBW children and 70 normal birth weight (NBW) children were enrolled in this cross\u2010sectional controlled study. The Pw\u2010d and QT\u2010d of the LBW and NBW children were investigated. Independent Student's t\u2010test, Mann\u2010Whitney U test, and \u03c7<jats:sup>2<\/jats:sup> test were performed to compare these two groups. Stepwise multiple regression analysis was performed to investigate whether there was a relationship between P\u2010wave indices, QT derivatives, anthropometric and clinical features, and echocardiographic parameters.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Age, gender, body mass index, waist circumferences, systolic and diastolic blood pressure, and echocardiographic measurements were similar between the LBW group and the NBW group (all P values &gt; 0.05). The following findings were recorded for the LBW and NBW groups, respectively: the Pw\u2010d (30 [10\u201350] ms vs 30 [10\u201350] ms, P = 0.977), QT\u2010d (20 [10\u201350] ms vs 30 [15\u201350] ms, P = 0.561), and QTc\u2010d (26 [14\u201354] ms vs 33 [17\u201362] ms, P = 0.866). No significant difference was found in Pw\u2010d, QT\u2010d, and QTc\u2010d in comparison between the groups (all P values &gt; 0.05). Pw\u2010d was related to left atrial diameter and QTc\u2010d was associated with left ventricle mass index even though they were within the normal
