A six months old infant with wheezing Case of the Month

Abstract

Aim: The risk of sudden death due to ventricular hypertrophy in athletes is controversial The relation of increased QT dispersion QTd with non homogeneous ventricular repolarization and arrhythmia in patients with hypertrophic cardiomyopathy is previously demonstrated We investigated if sports related ventricular hypertrophy causes such an abnormality in ventricular repolarization Material and Method: Twenty eight swimmers and 20 healthy children between 9 and 12 5 years of age were evaluated by history physical examination 12 lead electrocardiography and echocardiography Heart rate QT interval corrected QT QTc QTd and QTc dispersion QTcd values were compared Results: Echocardiographic measurements of swimmers were within the normal limits according to their weight However the interventricular nbsp; septal nbsp; thickness IVSd nbsp; left ventricular nbsp; posterior nbsp; wall nbsp; thickness LVPWd nbsp; left ventricular end diastolic diameter LVDd left ventricular mass were significantly increased in swimmers compared to the control group p lt;0 0001 0 009 0 046 lt;0 0001 respectively There was no statistical difference in terms of heart rate QT interval QTc QTd QTcd Conclusions: Absence of increased QT dispersion in athletes indicates that the ventricular repolarization is not heterogeneous and the arrhythmia risk is not higher than the normal population in this group Turk Arch Ped 2007; 42: 117 20 Key words: QT dispersion athletes heart sudden death arrhythmia
