Urmărește-ne pe DiscoverStudiul, realizat pe voluntari sănătoşi, a relevat faptul că ritmul cardiac a crescut îngrijorător de mult pe măsură ce doza de citalopram era mărită. Mai exact, electrocardiograma (EKG) a arătat prezenţa sindromului QT prelungit. Intervalul QT se calculează pe EKG de la începutul undei Q până la sfârşitul undei T.
Sindromul QT este deosebit de periculos deoarece poate duce la tahicardie ventriculară sau torsadă care, la rândul lor, pot degenera în fibrilaţie ventriculară sau moarte cardiacă subită.
Prin comparaţie, astfel de anomalii cardiace nu s-au observat în urma administrării de Prozac, Seroxat şi Lustral, medicamente antidepresive folosite pe scară largă.
