Effects of fluorosis on QT dispersion, heart rate variability and echocardiographic parameters in children

Abstract

Endemic fluorosis is a risk factor for decrease in calcium and FT4 levels, increase in sodium levels and QT prolongation. These findings might be related with some cardiovascular system dysfunctions such as arrhythmias or syncope. Subjects with fluorosis should be monitored in terms of long QT and QTc intervals.
