Cuore e Turner: cosa c’θ oltre la coartazione?

Heart and Turner Syndrome: what's beyond coarctation?

Gennaio 2015 - pagg. 57 -58

Abstract
A young woman affected by Turner syndrome undergoes periodic cardiac monitoring. Her last ECG documented QT prolongation. QT prolongation is reported in patients with Turner syndrome. This electrophysiological abnor-mality is probably due to an intrinsic defect in the regula-tion of the cardiovascular system. Although a long QT is more likely to be found in these patients, no severe life-threatening tachyarrhythmias have been described so far. Paediatricians should reassure Turner patients about the prognosis of this electrophysiological abnormality while recommending the cardiologic follow up.
