Abstract

Long QT syndrome, whether genetic or acquired, is closely associated with arrhythmogenic potential and consequently with syncope or even sudden death. This case report concerns a 77-year-old female who attended the emergency department for right-sided hemiparesis, diagnosed with ischemic stroke. She underwent Holter monitoring for paroxysmal atrial fibrillation, where an increase in the QT interval was found, which triggered a Torsades de Pointes by R on T phenomenon. After investigating the cause, it was found that the origin of the increase in the QT interval was iatrogenic. The drug that was influencing this change was Sotalol, which after being removed from the therapeutic table, reverted the QTc interval to within normal values.
